00:02 I've been gravy. What? Okay. Thank you. Hey folks

00:54 . Mhm. Oh, okay. . Alright. So we are winding

01:13 today and thursday. That's you. um so we're focusing on today And

01:23 is different infectious diseases. Um so schedule is open for example four,

01:29 is maybe 10, 11. Um remember it's not comprehensive. Just more

01:40 chapters 23 and 26 uh do That's huge smart word, do sunday

01:48 then there's A few days later chapter And so you can quit. So

01:55 uh more comprehensive. That'll be 20 questions opening through thursday through sunday.

02:08 . And uh let's see um so let me just mention that I

02:16 I had it in here. Uh . I posted I don't have it

02:25 , but I posted um the um make sure to have it thursday.

02:36 shouldn't see you last time. The the list of pathogens that I had

02:41 great example of the table how you want to organize it. So I've

02:46 that the list year already has already it separately. But also looked at

02:51 table for those that have had a of questions about that. Just to

02:55 us. Let's see added what it like. You're just doing that

02:59 Remember it's just a table that has columns pageant and one disease. It's

03:05 an example. You may want to more columns to that, but just

03:08 way to organize that material, 26 handling this honestly. Probably mostly memorization

03:15 . Right. What's the pattern? disease or just some of the various

03:19 that are important. Okay, so table is one way you might want

03:25 do it. Okay so it's available in the lecture notes folder. You

03:30 for it's called disease table example. you can take a look if you

03:36 . Um Okay uh any questions. , so we will have to finish

03:48 the last bit of 25. So looking at this question. I'll kind

03:55 elaborate on that. Okay uh kind this is really discovering a number of

04:01 we talked about last time. So number 25 is all about.

04:07 the pathogen is what it can do they can do to cause disease,

04:12 their physical chemical barriers etcetera. Um obviously there's a I've summarized there's also

04:21 narrow list of the various factors um of course it was used to

04:29 Get through different defenses. Okay. We ended last time with Okay,

04:39 sailor path. Right, so you're I'll finish up with the uh strategy

04:49 of extra sailor pathogen, Jack. . Okay let's see what we

05:32 Okay, so the consensus is h a look at this in a

05:40 Let's see potential routes. That's certainly that is. So um puncture wound

05:46 can occur. Surgery, certainly anything injection of bite that fits invasions of

05:53 related to intracellular pathogens uh c is as well. Um Were born?

06:02 transmission is fairly common and respiratory diseases it's certainly very common comic hold

06:12 flu etcetera. Covid. Okay so you know Thompson associated with gram

06:20 yep the chinese. So that plots mike in an object right? In

06:27 part of the contact and direct Mvs true as well. So

06:33 H is correct here. Okay um again here is like the the list

06:41 different factors we've gone over. We're to finish up with down here in

06:47 box those guys. So um remember there is a set of pathogens

06:54 Of course living viruses. Early, earliest semester. It's obvious that that's

07:00 they are but we focused more here bacterial types that can against side

07:07 And so the purpose not to replicate use them as a tool to

07:13 Rather there there used used to hide to to spread to other cell types

07:19 penetrating deeper into tissues. So that's we call these the faculty types.

07:28 . Many of these are um intestinal that we'll talk about. Maybe they

07:34 certainly thursday. Okay so let's look this last group here. Okay.

07:42 ended on this question so we know was it was this was the answer

07:47 . So it's a careless factor specifically staff that the um and it's a

07:53 I'm gonna visit here in a So I'm just going to this.

07:57 we're talking here about extra second They don't have the capability to get

08:01 of the cells? They must be their infection infection cycle outside cells.

08:09 they have different strategies to kind of the immune system. Okay, so

08:16 of course is a capsule is uh we hide and it's a covers will

08:24 be the outermost covering instagram, native the membrane, gram positive, covering

08:31 pepper like hand layer. Um and it can cover engines. It can

08:36 it someone to visit. We can it less able to be sensitized.

08:41 , this thing here, hyaluronic acid . So the capsule material, it's

08:47 play cycle, right? It can a mixture place acolytes and protein like

08:52 in there. But the ironic as capital is particularly special. We see

08:57 in the Two experience. You see , we'll talk about those uh to

09:02 the meningitis canceled. Um The hyaluronic councils remember hyaluronic acid itself as a

09:15 in your body. Is what holds epidermal cells together for one of the

09:20 that hold together. Right. And if you have a capsule made that

09:28 , will that capsule then be very know, Jack. Yes or

09:37 That's something for or would be less to do that. We're likely less

09:46 your body thinks it's part of your . Your body. That's that's what's

09:51 your body. Your immune system is to seeing that. All right.

09:57 um are you speaking right to to that? you use your own materials

10:03 to construct their things and make them um able to be detected.

10:09 So um so you see that particularly the streptococcus pneumonia capsule. Um

10:18 Okay. You can destroy some other are all have and counteracting extra cider

10:26 . Right? So if you're an side of pathogens, what do you

10:29 ? Well, simple things. So the I. G. A

10:33 geese was one of those. Um you're particularly respiratory pathogens that really for

10:41 most part require adhering to your newest of the respiratory system tracked etcetera there

10:49 wanted that would likely have something like to counteract the effects of remember idea

10:54 there in the new cultural secretions to neutralizing antibodies that bind to the micro

11:02 thereby the micro can't bind to the memory. So they can that was

11:08 um you know their ability to because have a way to destroy the And

11:15 from the previous diagrams of protein. Okay, so that's a way also

11:23 get rid of antibody effect. so to have this protein basically is

11:31 it buys the Fc portion of the . Let's remember the antibody binding sites

11:36 gonna be here right here. And this portion is the FC region.

11:47 . So if you have a way buying that. All right. Ah

11:53 that's what this protein in material does staff. Okay. And so now

12:00 energy of binding sites are out here they're not doing anything to the to

12:03 bacteria. If you can't destroy everybody will just make it not work

12:09 different one. Alright, So there's urgent bynum sites can't bind to

12:14 It's certainly do anything. So um Yeah, the strategy. So if

12:21 and anybody's binding to that so that course promote optimization. But this is

12:27 way to to stop that. Um And then uh let's see.

12:33 praise you just mentioned that. Let's some pathogens. So something cause various

12:40 they produce. Um can use apoptosis macrophages or neutrophils. Um And then

12:49 faith variation aspect. So again, you're an extra senator pathogen, you're

12:55 able to hide and sell the immune . You do these things like destroying

13:01 or make them otherwise not useful. uh change your bandages on the service

13:09 you go undetected. Okay. Whether playing capsule over or changing them.

13:16 ? So we saw that 10 The ability to have multiple forms of

13:23 engine that switch between So whatever about belt buying time concept. Right?

13:30 both ways we can, you know there. Slow down brother with passengers

13:36 our adaptive immune system time to catch . They pathogens can uh hide themselves

13:45 . All these kinds of mechanisms aren't So there's a limitation to it will

13:51 for a while. Okay. But , knowing how fast back here it

13:55 grow. They don't need that much to proliferate and spread. So again

14:00 both perspectives us and then it's buying , you know, it's a it's

14:06 thing that both can we end them utilize. Okay. So um.

14:13 . So this then closes out the patrons can do to support our defenses

14:22 gave questions for you. Okay. so the last part of this entire

14:30 will be looking at different diseases and diseases obviously. So we'll break it

14:36 in terms of systems. And we're not looking at every single just

14:40 kind of giving away sampling these things at least cover some of the things

14:47 at least one or two things in system can stop tissue respiratory get gi

14:54 into a urinary. Uh Just one . Um And cns athletes. And

15:02 uh we may get we'll get through on tissue reference respiratory system. Maybe

15:10 . I. Tract is not all may be happening, but um then

15:14 see the rest of thursday. So this section also has a little bit

15:21 . Oh okay. Patching list. , so some we spend more time

15:28 on some things than others. I don't have a lot to say

15:34 . Um And to me but political example. Um But I do have

15:38 to say about the box. so give me some on some.

15:44 so much right? Um But so that's the list. What to

15:50 . Okay. Grand reaction morphology disease , uh, feature. So,

15:57 know, for most of these, , there are some that have not

16:02 futures are only, you know, , you find with a certain

16:07 So for example, uh, right? We have claustrophobia and tetanus

16:16 forms. Right, Okay. uh, you know the ones that

16:21 viruses, obvious, Rhona virus, virus. Okay. But you can't

16:27 rambling on those. Right? So that. So, um,

16:31 as we go through, uh, we'll point out kind of the significant

16:36 about them. Uh, here's the . So that's the table. Certain

16:41 . Again, he'll have to do . But just the idea if you

16:45 to organize this information. Okay. uh, I think we're gonna start

16:50 start with a question. Okay. while you're answering this, let me

16:55 this pool and this number visible. . Um, so we're not or

17:05 . Thanks. Um, so remember um, critically needed. About very

17:16 , of course. Right? to, you know, particular diseases

17:22 where there are vaccines available or and that there's a threshold of,

17:29 , you have to have. I actually is one thing. But then

17:32 two is the majority of people vaccinated get the herd immunity effect.

17:41 So, um, in the universal like 75%. Okay. Um,

17:50 has to do with Because hey, going to get 100% compliance for a

17:55 of reasons. We have vaccinated. act as a sinks to absorb the

18:03 agent unvaccinated from, you know, , the apartment disease. Okay.

18:14 , uh, so we have Yeah, it's gonna be tetanus is

18:18 communicable, right? That's really what immunity can only affect, uh,

18:27 that are communicable penance, Personal personal . All right. But these other

18:32 are playing covid uncertainties. Personal person as it flew and many others.

18:39 that tetanus. Okay, um, is acquired through to be a functioning

18:47 , contaminated with soil gets in your and those reporters germinate, liberate.

18:56 , but you're not going to cost tell somebody and give them tasks.

19:01 . Not unless you take your stepped a rusty nail and um, moreover

19:08 objects down dirt and then you punctured you like just take your foot and

19:13 it on. So I do spread . Okay. So the point

19:18 it's not communicable disease. Okay. again, I'm not gonna spend a

19:23 of time on this. We've talked this already. So the point here

19:27 these diagrams is the ones that are our, our sick and our contagious

19:37 . Okay. On the left And blues are unvaccinated people. Yellows

19:44 vaccinated. So we have 123 vaccinated . Okay, vaccinated, healthy.

19:51 , you have more non vaccinated So this guy has six spreads

19:56 You don't have enough of a sink that person. Okay so of course

20:01 get lots of more red people, people getting infected right over here.

20:06 of yellows, lots of people that been vaccinated, right? So you

20:09 the barriers between unvaccinated blue and between the movement basically. So there's space

20:18 where you have lots of vaccinated people your infectious agent and you contain the

20:27 . So you know the bottom line um get back stand to but again

20:34 to a certain threshold to a cheaper you can see cable last. So

20:43 the r values are kind of a of contagious and so you would be

20:50 roo value percent to get that herd . So um I already questions about

21:01 and I said I mentioned it last . So let's look at diseases.

21:08 so we're gonna start with skin and tissue. Um One of the more

21:12 types of really not a serious disease um staff for you. So you

21:19 , there's there's a epidermis, that , but that's the other problem staff

21:27 uh can't understand but it's relatively Okay, that's the diseases caused by

21:34 gonna be born. The staff grand positive. Great black clusters.

21:40 uh and there's a boils and carb which I think are in the in

21:49 same thing but there's things like uh . Um uh they're all about different

21:59 of skin infections, stein's through the infected eyelashes, physically. Lightest hair

22:05 is getting affected boiled are typically or kind of puncture wound that introduces the

22:15 into the skin. Uh remember staff coagulates, the staph and strep which

22:22 come next have a few rubles factors common, particularly with the toxins like

22:29 um and others. Um and so typically can produce a heart, not

22:36 call it. And uh it's basically white was kind of clotting and formulated

22:42 to around the staff. And so uncommon to have to develop her lengths

22:47 oil right to get that because that will fill up with a sells itself

22:53 us. Okay, in order to at it treated, you didn't have

22:58 drain it try. Um And so toxic shock syndrome. So that was

23:08 was I still haven't found that, it was traced to others. An

23:13 of this, it was 2030 years traced to female uh napkins, tampons

23:22 was super absorbent but in creating an that promotes the growth of staff and

23:28 particularly the types that produced this toxic super or super ranger effect will overrun

23:35 system. Alright, I think of like a almost like a body wide

23:40 response right? And that will um course can lead to shock and cause

23:46 . And so of course those those products are taken off the market and

23:51 we saw severe reduction in the in in the in these types of

23:56 But um there are you still occasionally this toxic shock syndrome here and

24:03 Um So most of colonial infections, ? This is becoming a bit more

24:13 mm hmm. Outdated and replaced by more current term that's abbreviated H.

24:22 . I. Does anybody know what ? Yeah. Hospital part. So

24:29 they're going to switch to H. . High because health care not only

24:32 in hospitals but of course it's mobile into people's homes for the elderly in

24:39 get healthcare. There's all kinds of beyond beyond the the hospital everywhere.

24:45 this explained at the time to help acquired. So what it means

24:49 okay, you go to the hospital you go to a clinic or what

24:54 you because you have, let's say have the flu. Okay, while

25:00 there, you come down with something or maybe just go you don't have

25:05 disease. You know because you you a sore back. Okay? And

25:11 getting into the hospital, right? you're mature you get in the hospital

25:17 then you require an infectious disease because in the hospital. That's the program

25:22 for more currently healthcare of Okay. you you you acquired that disease as

25:31 function of being in that clinic, gave it to this thing without.

25:35 . And so this is a this an issue for hospital. Um And

25:41 that's why of course is all kind right ah disinfection to the max,

25:48 ? To minimize these kinds of and so the staph aureus um about

25:55 of these infections are attributed to staph . Um There's about three or four

26:02 that are defined more often than and that's one of them. Um

26:07 it also correct that, you it really likes to transmission because you're

26:11 the hospital, Right? But people . So you have reservoirs right of

26:18 that are harder in these cabinets. . Artistic. And so then,

26:23 , what was the connection? between the patient and patient health

26:29 So those I hope. But, know, the number one thing,

26:39 know for healthcare workers in hospitals of , get monthly meetings and he keeps

26:45 on sanitary practices and you know, practices to use. What's the number

26:49 thing that really limits limits of these acquired infections? Very basic washing

26:58 That's right, washing hands is the that is preached, you know,

27:04 Yeah, to minimize these kind of . Um The uh and also another

27:11 that policies are devices catheters, uh to um uh replacement parts. Since

27:21 are hard. Now there's like these come prepackaged sterile packaged and if not

27:26 properly, whatever because it goes into the skin. So you're not handling

27:32 ? S epic way that you can um staff right into these areas.

27:41 , um so that's what infections And the methicillin resistant staph for is

27:49 problematic. Now there's a bank of and resistant types of multi drug resistant

27:56 . So it's um that's the other because in hospitals you administer antibiotics and

28:01 all kinds of opportunity for resistance to too. So it's a something that

28:08 are. So they have to be top of the monitor. You

28:12 any kind of things that pop up the hospital, find out what it

28:16 . Can we know what's susceptible to periodic wise and stuff like that?

28:21 really keep a hold on this and don't want to go to the hospital

28:25 you have some other condition. And while you're there get get an infectious

28:29 . All right. That's that's So um impetigo and scarlet skin

28:36 So as we're getting this from staff strap, okay, there's gonna be

28:42 skin infections that relate to, let's depth, right? So depth of

28:50 infections. So superficial layers, dermal underneath uh deeper layers, Right?

28:57 there's different types of infections, Scarlet skin syndrome are more superficial layers

29:04 skin, upper layers of skin. . And any of these types can

29:09 through this is the basic abrasion. know that doesn't get really clean

29:15 Then they kind of they begin to in there. Uh and and some

29:20 have different different types of toxins and come into different severity of the the

29:26 of penetration into the skin. so every time I go as often

29:31 cities often found kids in daycare uh kids of course are not the

29:38 , right? Um and so scratching skin or whatever with dirty hands.

29:43 can lead to impetigo. It's kind like a rash, like ling um

29:51 there. Again, superficial layers. toxic countries can lead to damaging the

29:57 the upper layer. And this kind disrespect it occurred. That's what they

30:02 this exfoliated pots. And you've heard exfoliation right? The skin help your

30:08 , right? This is this is really that Okay, this is more

30:13 little more serious than that. But we're talking superficial layers, not something

30:18 jeremy is going to be super but nonetheless you want to take care

30:22 it. And really it's just you , cleaning the cleaning a wound or

30:27 when you first have it and doing will really be the best way to

30:31 these kinds of things from getting Okay. Um so staph aureus need

30:36 go to again and we went through before um but again, you know

30:43 many of these infectious agents going to talking about. They they're gonna have

30:48 particular types of girls factors which I so streptococcus, we talked about that

30:55 protein a struck the caucus uh grandpa also but streptomycin chains chains of gram

31:04 oxide. There can be variations that be uh difficult oxides well prepared is

31:13 it's in pairs. Alright. But are you have these changes of several

31:19 . Okay. So historically uh streptococcus species. The months dramatically important have

31:29 characterized by their by their growth and on blood off. Right. That

31:35 been as it was established like in 50s I think. And it's been

31:40 this way ever since um because they eastern losses. Or he also has

31:45 great apartment blood cells. Okay. it's found that different stretch species can

31:51 this differently. So if some of can completely to destroy lice red blood

31:58 even clearing zone like they wanted a somebody is really cute and this is

32:03 over plate and basically just a cotton until they a beta hemolytic stripped and

32:11 it right. And then did the the alpha sign in the so this

32:22 a complete clearer which is characterized beta . This is more kind of a

32:27 color and so is partial. So kind of really just oxidizing the iron

32:34 hemoglobin which is kind of a reddish , partial license, complete him

32:39 So G A. S stands for A strep group A strep are pretty

32:48 there there all all members have have just because they don't like but they're

32:57 patterns in that group. So the one that has multiple types of

33:07 Okay, it's a nasty. So you have gone into the doctor with

33:12 sore throat and then do a throat and you see uh this on the

33:18 . Um So it tells, okay say it's a it's probably group a

33:24 likely because this is the one that strep throat. All right. So

33:28 look in the microscope and see see then that's pretty definitive but fairly presumptive

33:37 that's you. So um and so look at the different groups and the

33:47 . Okay again this beer dances another term but it relates to the is

33:55 oral back your cavities ah Among others that's hard right there. Um um

34:06 of bacteria that cause um diseases of math like cavities uh periodontal disease

34:16 But this is one okay particularly not much periodontal disease which kind of gets

34:23 the this is more on to surface cavities in general as staff are to

34:35 fermenters ensures. And um in the um uh presentation creates acidity right?

34:44 that can also break tend to break the enamel uh leading potentially to Calgary's

34:52 teeth. That's uh that's what that . It can so dental procedures like

35:01 reason people um root canal that these procedures where bacteria in your mouth can

35:14 get into the blood I guess obviously are invasive procedures right? And um

35:22 is one comes by you can so gets the travels I guess on your

35:27 valve. It kind of sticks there it can cause information leading to a

35:33 of problems with your heart function. um That's of course what you when

35:40 get it would be too full for reason. Okay or other oral

35:47 The money I also that that's that's in our discussion on purgatory infections.

35:55 I'm not the sandwich now. I'll . Um But we've already meningitis is

36:00 thing um about that in a So a number of different diseases.

36:07 and and Phillip Pappas is one that's little bit different. It's A

36:11 I. Tract. All the other are kind of most of the skin

36:15 infections but this one causes gi tract . Okay so um okay various

36:24 We've seen these before. Okay the overlap with staff here in a number

36:31 experience factors. Okay um remember that prevent proper activation, adherence as

36:40 So um the short drugs, what call meningitis is kind of the I

36:50 the fancy term for sore throat. so stressed. Oh certainly. Uh

36:55 so let's just go to that real . I'll come back to that.

37:01 . Okay the we talk about sore in the context of respiratory tract so

37:10 not there yet but we'll stick with skin infections now but struck what's up

37:16 we to these other conditions like um fever like um these superficial skin

37:25 Okay it can travel from there and cause these other kinds of issues.

37:30 and so romantic fever. Right, this is about immunological cross reaction.

37:36 , so antibodies can are produced in to an antigen. Okay, if

37:45 encounters another engine it's very very similar structure. Right then it can't react

37:54 those cross reaction. Right. Remember back right? With Jenner and tap

38:01 smallpox. Right. So the the cowpox works on smallpox and is

38:09 less dangerous because doesn't cause disease in . Okay. But very similar.

38:14 they invited can work on both. here um the m protein of strap

38:22 is has similarity to um these heart proteins. Okay and also to uh

38:33 collagen fibers and joints. Okay, causing arthritis. So anybody's create anybody

38:42 in proteins and strep can they cross with heart muscle and heart muscle

38:48 Uh in some cases to connective tissue joints get very similarly in between the

38:57 and of course you cause issues. , This can cause uh actually cause

39:02 , it was the negative tissue causing in your joints. So with the

39:09 for that it's called is that name they got the secondary immune response antibodies

39:17 the pathogen, specifically the n But then there's similarity to another engine

39:22 anybody to also react. But those kind of like uh conditioner in

39:31 Okay, um now uh so you're simples and necrotizing. Okay, so

39:39 looked at um uh tiego scalded skin uppermost kind of layers of skin.

39:50 so now we're slowly getting deeper, , deeper. Ok so the simplest

39:55 at the top picture. Okay that's kind of really deep red rash.

40:04 let me see here. Okay and we're getting a little bit deeper comes

40:10 uh what they called thermal layers and , deeper than that, deeper than

40:16 is advertising fast right here you see was he involved there? So um

40:23 it can start these can starts in cases from strep throat. Okay.

40:29 um but more often very simplest begins kind of an abrasion to the skin

40:37 not really created then then my dear and particularly they have a battery of

40:45 . Uh that's kind of what separates my degree of toxins possessed.

40:51 So more toxins uh and he's and like you're on a date college in

40:58 etcetera penetration. You know obviously you see how deeply penetrating is here from

41:06 fasciitis compared to your simplest but kind just um variations of each other but

41:13 different in terms of how deep, penetrating it becomes china. Um the

41:24 any questions and don't throw things happening it's um the other question is

41:31 Okay um Alright so let's look at breath here and get this cooper

41:38 Okay let me this over here. most respiratory um infections and gi tract

41:50 are blank in nature, bacterial fungal the zone or viral. Yeah fire

42:07 all this stress. They all have same it. Uh No so even

42:17 strep papaya genies strings they'll vary in types of various factors they'll have.

42:24 so it's If that will vary. . No no one sorry strap will

42:30 all of them and they will vary within a species as well. Uh

42:39 the enzymes. Mhm. Yeah more you uh I would say can you

43:00 you do it one more time? think I missed the last part.

43:07 . Yeah the stress. Okay. . Right. Right. Yeah.

43:21 terms of yeah in terms of individual so a mutant versus yeah mutants will

43:28 a different collection, correct? That's . That's right. That's right.

43:33 Okay so we were able to split bacteria and environment. That makes

43:39 Okay the answer is so um uh and in generally the viral versions tend

43:55 be more prevalent and less severe and bacterial origins are the ones that is

44:02 severe. Mhm. Think of common versus the flu or pneumonia. Okay

44:13 call this differently. That's benign. not gonna say in every case.

44:17 true but most cases that holds Okay G. I tract infections stomach

44:25 so that's the viral nature um and prevalent and but again to be not

44:32 serious as the bacterial versions are. so um so respiratory tract infections.

44:41 . Um Where bacteria come into play uh is um and this is not

44:51 for G. I. Tract infections infections it's a problem that you have

44:56 viral um uh infection and then you and then bacterial secondary infection occurs

45:08 E. Pneumonia. Okay uh And pneumonia is worse, pneumonia is often

45:15 required hospitalization. Okay Whereas the flu know you generally have to go to

45:21 hospital for that. Um But yeah being bacterial bacterial infection, viral

45:27 bacterial type is typically worse. Um And so we rate this down

45:34 the upper and lower respiratory tract So here is stripped again so strep

45:39 is in the context of so but this can once you know while in

45:51 mode in some cases the Strip Cannon produced another disease. Not uncommon is

46:01 scarlet fever. And so bronchitis, , strep throat. The Scarlet fever

46:11 one that's uh generally that's it's not not common to find that in Children

46:19 10 years old killing and three younger . Um So this original manic toxin

46:25 on vocabulary these and violates them like dilates caballos. And what that does

46:32 of course skin right? And it this verse bribery like red color.

46:42 one of those diseases that's um scary of the way somebody looks with

46:47 Okay. But is everything it's something get over with pretty pretty quickly but

46:56 does look kind of shocking. And see some money with this. Um

46:59 really deep red skin rash. You do a little fever. But it

47:04 something you you can easily treat. diphtheria. Okay, so diphtheria certainly

47:14 the earlier part of the century, previous century, 13 20 thirties,

47:21 diphtheria was just decimating Children in And uh that that there was one

47:32 the cases of where you saw the effect of vaccination, one of the

47:37 effective diseases where you saw that. because cases cases of serial killer,

47:43 dramatic drop within a year or so a vaccination. And um it's so

47:52 back character is one of those that the weird uniform non uniform shapes,

47:58 ? As he's club shapes and irregular forms. So it says that morph

48:06 . Okay, so they are gram and as you see kind of a

48:11 forms here again, just they're not , they're not all cocks ID.

48:15 rods are kind of just weird shapes this characteristic of that group. So

48:21 theory to as I mentioned, the and the the current vaccine is called

48:31 . Dap. Alright, that's it's it's changed in name and in structure

48:38 well. Man, I'll mention that in a second in the context of

48:42 one. So the piece of the is tetanus. D is that

48:45 P. Is pertussis? Okay, it's a try three headed vaccine,

48:51 to speak. Trying again. D . Okay so we'll we'll revisit this

49:01 the context of pertussis. Okay but look here. So the theory is

49:07 of something cold like symptoms in the . Um There's a there's a toxin

49:14 . Okay this characteristic pseudo membrane that okay so early on the fashion.

49:21 it's hard because it's like a sore typically include a fever. Um Then

49:27 produces a toxin produced this kind of and throat. It can cause a

49:33 in the back of your throat and your body responds to that and reform

49:38 factors and things. So and that the fire of reform that trap also

49:43 caroni bacterium agent together right collection of and finders and fluid comes together to

49:53 that gray pseudo membrane. Okay that's distinctive for um the theory is a

50:01 membrane. So back to the the . Alright that's terrorism future. I

50:06 what went right theory. Okay so can't get it can get big enough

50:14 membrane where it can impair breathing and can you can you can have quite

50:20 problem trying to breathe that's blocking your obviously. Right um now it has

50:27 toxins that will get into the bloodstream it can cause the worst aspects.

50:33 I believe it's a toxin that inhibits synthesis so that of course will be

50:39 for the target cells that are taking hit but it is of course completely

50:46 through vaccination active cases can be treated antibiotics. But nowadays this theory because

50:53 vaccinations theory is not prevalent. It's obviously killing Children like it was several

51:00 decades ago but um mild. It's a skin acquired for the skin but

51:09 uh do not talk the same type symptoms as as the respiratory form

51:17 Um Now uh let's see lower respiratory fashion. So so another multi toxin

51:31 . Okay so the border teller pertussis negative short run. So when you

51:37 the trump koksal bacillus that typically means short rod shape. Um So remember

51:43 innate immune system defense that mucosal Salieri . Right so cecilia you trade your

51:50 constantly. Uh plus the production of . Right, trap any part particulates

51:57 whatnot keep in mind your lungs. the this has toxins that will actively

52:05 the cells that produce to Celia. so you see in this picture

52:12 It sells right these long projections and yellowish are the uh is the pertussis

52:20 ? Okay and so there's kind of couple of stages that goes through so

52:25 have trade real toxin that damages these cell types. Uh professors toxin that

52:31 think is a one that the image synthesis. It can cause more systemic

52:37 that trade real toxin is more specific this area here. The toxin systemic

52:44 orphans and whatnot. Um So the states of Kotaro stage lasts for a

52:51 of weeks, people just looks like common quote, Okay, you may

52:56 slight fever. Uh, you it's a lot of these symptoms

53:00 you know, fatigue, cold, symptoms, headache, these kind of

53:06 , uh not nothing serious yet, during this Kitaro stages when these toxins

53:11 accumulating, Okay, so they reach level at which then they really produce

53:16 worst effects in the paroxysmal stage. . Um, and so if you

53:24 lacking the city itself, so this of this musical Salieri escalator is not

53:34 . They're silly. I want you're you have mucus that's accumulating.

53:40 . And you obviously are having trouble and coughing violently. Okay. And

53:46 it's really uh bad for infant very Children because instant, particularly if it's

53:55 violently. What what often happens is baby has uh neurological issues because the

54:04 shaking causes, you know, uh informing the brain that causes impaired brain

54:11 . So that's that's that's the worst obviously, but it's it's not,

54:16 unavoidable because of the coughing and the spasms and things trying to breathe.

54:21 . Um, it is people with , but certainly the vaccine is what

54:27 can do. Um, and to over. It takes a few months

54:33 as well. So, um, , in terms of the vaccine,

54:39 , it's changed in terms of form as well. Um, in 2012

54:48 was seen a Rise in professors among 12, 13 year old Children and

54:58 would have been about five years since were a pan the first vaccine

55:04 the last booster uh, for for the mexican. And so what's going

55:12 here? And apparently the immunity when that after a few years it was

55:19 long lasting. So it was attributed the vaccine. And so they went

55:25 a different format to their self So it's a it's a it's certainly

55:30 an antitoxin type toxoid vaccine because diphtheria tetanus toxin and percussive toxin. That's

55:39 the vaccine is two. Uh, anyway, it turns out the construction

55:43 magazine is what helped increase the community and of course the cases went down

55:50 they developed the vaccine. But it to show you that um, you

55:55 , even with vaccination there after a , you know, you still have

55:59 have to um, that's, that's one thing to talk about here is

56:06 , all infectious diseases in this country law have to be reported.

56:13 So, we know that there are of, of all the things we're

56:19 about 10-26 certainly are such as these are reported. You have to

56:24 So we have this whole database of of things that, you know,

56:29 all kinds of infectious diseases. So can keep on top of things like

56:34 . Right? So we've seen up cases we go, what's that

56:38 Right, so we have a date time to see a as a problem

56:42 then just find it solution to. , so uh those are interested there's

56:51 it's called more liquidity and mortality weekly . W. R. R.

57:00 report. Um a list of all types of infectious diseases that are going

57:09 in the country and around the Uh the end of the year is

57:12 use the whole yeah all the data the entire year but you may find

57:18 mmwr morbidity and mortality. Weekly Okay. Um Any questions?

57:29 let's see your hand. Starting to . That's fine. Um Okay,

57:36 . So pneumonia is caused by a of things that viral pneumonia is bacterial

57:45 . Fungal pneumonia, I think for old evolved you see a list

57:52 Number one on the list. so again, strep change. This

58:00 is in pairs actually. So parsimonious . Very positive. Okay. Sick

58:06 Okay, um uh spread by airborne of course. Um so secondary

58:14 so not uncommon to have to say first viral flu and in the

58:25 Okay, what is it you start run its course right? Simply don't

58:32 any kind of treatment, just like most viral diseases as it runs its

58:36 and you get over it. what is the one thing they tell

58:40 where you have the flu to what, see how to do what

58:48 , drink? Hydrate drink, drink water, drink juice, drink

58:53 okay hydrate yourself? Of course some that diligently but related about it.

59:03 And so when you see the effect that can be um the so remember

59:09 to the mucus Salieri escalator. So the mucus when you get dehydrated

59:16 having got over the flu your mucus get um fit. Okay not the

59:23 viscosity let's say okay. And so that kind of somewhat impaired that

59:31 right? And that's that can be opportunity for a secondary infection to

59:37 Okay come in. Right and then worse damage. Okay and so what

59:46 will do it will get into the . And so typically it's what we

59:50 low bar pneumonia. You get. affects one or the other of the

59:55 of the lungs. It's not common affect both. It's either one or

59:58 other. And so what happens is gets in there and it will induce

60:06 will begin to cliff. Right? you do have um fluid that's around

60:13 remember the lungs. And then these um small piece uh clusters of little

60:21 were at the al right? There's surrounding them um could be nutrient

60:26 And so the stand the streptococcus pneumonia they will begin to proliferate. Their

60:31 increase, induces a new response. you're gonna have these our be older

60:37 running around right? You'll start to the threat. Famous of ties but

60:44 induce you know the unsanitary response production psychic clients et cetera. Right?

60:51 that occurs then you will get a of cells will show up but then

61:00 so you have fluid build up trying fight this infection, right? And

61:07 what causes you know we need to paired. Right? So what food

61:12 up in the lungs. It can not uncommon to be hospitalized because of

61:17 . And uh of course when you to shut it off, shut down

61:22 infection as soon as you can get still effective penicillin and just in time

61:27 showing up. Um But you don't to get you don't want to worsen

61:33 obviously you're breathing can be impaired and you can affect uh when breathing becomes

61:38 you can affect other other parts of body. Obviously not getting enough

61:42 You likely would have to go on . So um but it's it's nothing

61:47 fool around with. And there was vaccine the vaccine is more for my

61:55 . Okay I've been told to get vaccine the last five years now I

62:00 get it. But like like with these infectious diseases the one that's most

62:06 are always very young. Very out those on the on the older side

62:13 . Okay. Yeah. Hello. you for that. That's right.

62:24 right. Um Oh okay. There's else I have to say here.

62:28 yeah, the bottom part. um, yeah, we'll talk about

62:33 nervous system happening next time. But will come up again. Not uncommon

62:41 ceremonial to progress. Um, spread the central nervous system. This is

62:47 second Neisseria. Meningitis is number one terms of causing meningitis. This is

62:52 two and it's not, it's not far behind. So it's only the

62:56 leading cause of meningitis. Um, , so here's the question.

63:03 so other diseases so far. so listen, so we had skin

63:13 soft tissue infections. So its staff , this area Bactrim mm hmm.

63:28 the telephone taxes and just finish up apartment. So what did the reservoir

63:41 best guess it really hits. It's evidence. Yes. Okay. Mm

64:16 . Yeah. Alright. Let's And truce. It is humans

64:30 Right? So you get the you get your throat, you get

64:36 , you get this and that blame familiar human contract. Um,

64:46 so legionella. Uh, yeah, disease. So this was um,

64:56 remember this from uh, 1976, huge in this country. Why is

65:05 ? It's a big celebration that That's just bicentennial, 200 Anniversary of

65:14 signing of the independence on July 1976, huge. Okay. All

65:21 up to the summer and they had kinds of Building on July four

65:26 all kinds of fireworks and stuff. ask your parents about it.

65:30 Our grandparents. Um It was uh , I remember that. That's the

65:37 . Uh even though I'm much older you are, does anybody know the

65:43 Rocky? Yeah, that's when that came out. Um The uh

65:53 And and it really coming in this outbreak before that, it wasn't really

65:58 of all the is kind of one these that's found and lots of parts

66:04 the environment. Right, soil, , et cetera. Um So this

66:09 atypical pneumonia. Okay, so typical is what you see with pneumonia.

66:19 . Typically a more serious form of required hospitalization or serious symptoms. A

66:28 is not that the medical deterrent walking . Okay. These because the milder

66:37 milder symptoms. Okay, so this one of those, although led to

66:44 deaths in this outbreak, but that's to another factor that will get you

66:48 a second. But so these guys gram negative, there are motile with

66:55 single for gel. Um They live a minibus typically. Okay, so

67:01 just get that out so you can here it's not that obvious really.

67:07 actually are inside of this media This has these right here kind of

67:14 together. Anyway, so let's look the living environment, particularly quiet environments

67:22 Amoebas. Um and they also had effect you there one of these uh

67:30 sailor faculty sailor uh type of Okay, so they'll get inside of

67:36 macrophage for example, do you remember invasions and put those in there?

67:40 that cell will engulf it. Um that's what listeria is of each

67:46 every. Excuse me. And so do you, what's the typical ground

67:50 here? Well, okay. I'm gonna go into the physics of how

67:55 h practiced um worked okay. But commercial um unit. Okay. Of

68:07 , weekends on top of the Uh so called what it's all

68:13 So you have these water towers that you have a Fanboy and unsafe to

68:21 and you have he has changed occurring produce cool air. So you're turning

68:26 thermostat on they see as a mechanism do that. So you have um

68:32 gonna have water droplets, aerosols in air. Okay. As a result

68:37 this process now, the source comes what? And water and cooling

68:43 Right. Yes. Those cooling towers maintained clean, properly disinfected. And

68:49 her on a regular basis. Then water in there can be contained these

68:55 of things. Okay. And in outbreak I mentioned earlier, That's what

69:02 was in the 70s businesses informational occurred hotel where these systems are maintained.

69:11 the spots as well hot tubs Also think I have a list here.

69:18 . There we go. Just an . Obviously don't memorize this. Um

69:23 every year this is just 2019. every year I said look at ever

69:29 year There was, you know, or 7, 10 dozen upgrades like

69:35 . Not big necessarily convenient, maybe people. But in some cases more

69:41 this is uh but uh you see common denominator, hot tub water

69:48 cooling tower pool and hot tub. ? And so um all coming down

69:54 the generic disease. Okay. Now As mentioned, the outbreak in

70:02 Okay, so um the uh the from let's go, people will tell

70:11 this conference was american League. So thing about the american legion is that

70:19 are veterans of previous wars. So that means overwhelmingly the members of

70:27 group are what young to surprise people you. Yeah, they're old people

70:37 like the perfect storm happening. So atypical pneumonia where it should be given

70:42 milder symptoms, but because we're talking older people will most likely had underlying

70:49 whether you know, whatever that may , Um and smoke smoking and correlates

70:55 , you know, getting worse symptoms weekend, there's likely wouldn't have

70:59 Certainly. So um so uh 29 died. So they traced it to

71:06 one hotel really. Um and the tower and the water contaminated with

71:13 So it was that with it's just in june uh june july time

71:25 Um Of course hot. Right? gonna have the ec y summer it's

71:30 . So a c running even so a chance for this to

71:35 Okay so um again normally most of will healthy systems will right out.

71:45 but if you if you don't then can be quite serious. And so

71:51 sentence you see they're short of breath nausea vomiting if it gets really

71:57 Again the worst effects coming to the york compromised people. Okay um You

72:04 treat with antibiotics. Um The but maintaining prevention of things to maintain these

72:15 a track systems and similar ones where rely on these water sources to get

72:22 part of the how the thing Okay. Um So what next?

72:32 any questions so far? Yes. correct. That's right. That's

72:42 Um The you know that uh I'm say I don't it don't happen.

72:51 not gonna ask you to list on test the symptoms and diseases because there's

72:58 lot of just relax. So I'm going to get that that thinking about

73:02 just happened there's some that are pretty if you have tetanus. That's not

73:09 symptom spasms you know but things like like malaise and fatigue don't don't worry

73:19 much about that. Okay. Um this is gonna be in the top

73:25 little bit about G. I tract . Um So let me open this

73:31 these bacteria do not infect your stomach intestines that you don't have to um

73:43 don't have to get into your The cells themselves do not have to

73:48 there, but they nonetheless can cause poisoning. Okay. So um what

73:56 you building this over um the microaggressions infections? Gi tract infections are mostly

74:05 to viruses, right? Um The worst effects of attract illness.

74:14 didn't intended to bacteria protozoa. All will mention a couple of protozoa

74:47 Okay. Yeah. Okay. Let's what we get. Mm hmm.

75:05 coli try um Who answered? Uh . Alright. How how does how

75:16 is it c it is c So you know so some of them

75:28 write is that that affects it's So does dysentery and Nicola there's like

75:37 then pathogenesis strep throat. So So I guess the only other option

75:44 arguing, correct? So, positive . Right? So this is you've

75:51 of the uh um potato salad at picnic and I got home when I

75:58 got sick. Okay so uh so could some staff already can produce uh

76:06 toxic. So back to the example the potato salad right to make potato

76:12 . Um You know you got your , of course staff can be on

76:16 skin, you can do this It's often your nasal passages and then

76:21 peeling potatoes and whatever else. And so then with the potato salad

76:25 out right nice at room temperature and from the staff liberating they grow.

76:31 produce toxins and toxins now sitting on of that detail salad. Then you

76:36 it, right? And so you sick so you don't get sick because

76:41 staff's getting into your got you get because they produce toxin that was sitting

76:46 your food. Graduate toxin is what the damage. Okay, so that's

76:52 one of those that you can think struck priorities. Obviously it's not artists

76:57 you e coli or salmonella shigella. are going to get foodborne or waterborne

77:04 , they suggest. But staff at oddball like the staph aureus, staff

77:09 not built to withstand going with your and surviving. So the toxin is

77:15 . Um we'll stop there folks, we'll finish up next time and uh

77:23 you then.
