Because I know your weekend won't be complete without it...

Here is the study guide from my most recent medical microbiology exam. And yes, it's 12 pages long. :)

Chapter 19 - Mechanisms of Bacterial Pathogenesis

1. Define each of the following terms: pathology, etiology, etiological agent, pathogenesis, colonization, disease, infection, pathogen, pathogenic, bacteremia, septicemia, toxemia, viremia, and reservoir.
Pathology – study of disease
Etiology – the cause of the disease (eg. The organism)
Colonization – bacteria growing in the body
Disease – change from a state of health
Infection – colonization with a pathogenic bacterium
Pathogen – disease-causing agent
Pathogenic – adj. for pathogen
Bacteremia – bacteria in the blood
Septicemia – bacteria growing in the blood
Toxemia – toxins in the blood
Viremia – viruses in the blood
Reservoir – where the pathogen “hangs out” naturally.

2. What is normal flora? Explain how normal flora could be categorized as: mutualistic, commensal, or opportunistic. What is a parasite?
Normal flora is the colonization of bacteria in out body that is normal and not harmful. They contribute to microbial antagonism, and may synthesize nutrients such as vitamins that help us.
Mutualistic – both benefit
Commensal – one benefits
Opportunistic – NF takes advantage of suppressed immune system to cause infection in an unusual location
Parasite – one benefits, other is harmed

3. What is the germ theory of disease? What are Koch’s Postulates? What are they used for?
Germ theory – germs cause disease. One germ, one disease.
Koch – to prove which microorganism is the causative agent of the disease
Isolate sample from infected individual
Culture
Infect new individual
When signs and symptoms develop that are the same as the first infected individual, the organism is the same, and can be concluded to be the causative agent.

4. Describe how each of the following is used to describe a disease (and explain what the term means): communicable, contagious, noncommunicable, endemic, epidemic, pandemic, acute, chronic, and latent.
Communicable – can spread from person to person (HIV)
Contagious – spreads easily from person to person (rhinovirus)
Non-communicable – cannot be spread from person to person (tetanus)
Endemic – at a consistent rate of infection
Epidemic – spike of infection rate in a given area
Pandemic – disease is worldwide
Acute – rapid onset, severe, then finishes
Chronic – slow onset, prolonged illness
Latent – person is a carrier, but shows no symptoms. Can flare up (varicella)

5. What is the difference between a local infection and a systemic infection?
Local – confined to one area
Systemic – whole body

6. What is the difference between a primary infection and a secondary infection? What is a subclinical infection?
1ary – first infection
2ary – infection after the 1ary, more susceptible to it bc of weakened immune system
Subclinical – no symptoms

7. Describe the following mechanisms of disease transmission: contact transmission (direct, indirect, and droplet), vehicle transmission, and vector transmission.
Contact:
Direct – person-to-person
Indirect – through an inanimate object
Droplet – cough, sneeze
Vehicle – food and water
Vector – insect bite

8. What is a fomite? What is a nosocomial infection?
Fomite – for indirect transmission
Nosocomial – acquired in a healthcare setting

9. What is epidemiology?
Study of frequency and distribution of disease.

10. What is the Center for Disease Control and Prevention (CDC)? What types of things does this agency do?
National Epidemiology Center (USA). Tracks infectious diseases, helps local health agencies during outbreaks. Publishes monthly reports.

11. Describe the sequence of events successful pathogens carry out.
Transmission to host, entry into tissue, adherence to target tissue, invasion/evasion, host damage, exit, transmission.

12. What are portals of entry? What are the possible portals of entry for pathogens?
PofE are where the pathogen gains entry to the host. Usually: mucous membranes (GI, GU, respiratory), parenteral, skin.

13. What are virulence factors? How does each of the following function as a virulence factor: adhesions, fimbriae, biofilms, capsule, cell walls of mycobacteria, toxins, and enzymes?
Adhesins – help bacteria stick to host tissue. Fimbriae and pili.
Fimbrie – “ “
Biofilms – glue to surfaces
Capsule – evade phagocytosis, poorly antigenic
Mycolic acid – evade phagocytosis
Toxins – host damage, direct (exo) and indirect (endo)
Enzymes – kinase, coagulase, hyaluronidase, collagenase, IgA protease.

14. Give the function of each of the following enzymes and explain how they can aid pathogens in causing disease: hemolysins (both α and β hemolysins), leukocidins, streptokinase, staphylokinase, coagulase, collagenase, proteases, hyaluronidase, and phospholipase C.
Hemolysins – lyse RBCs
α – complete lysis
β – partial lysis
Leukocidins – lyse WBCs
Strepto/staphylokinase – break down blood clots, gain entry
Coagulase – formation of blood clots, wall off from WBCs
Collagenase – break collagen, get deeper into tissues
Protease – break down specific proteins, eg. IgA protease.
Hyaluronidase – break down hyaluronic acid, get deeper into tissues
Phospholipase C – hydrolyses lecithin (in tissues)

15. What are exotoxins? List the examples of the following types of exotoxins discussed in class and explain how they affect the host: cytotoxins, enterotoxins, and neurotoxins.
Exotoxins – released by the cell. Usually G(+), but can be G(-).
Cytotoxins – damage cells
Erythrotoxins – damage to capillary cells, cause blood to leak out (S. pyogenes)
Enterotoxins – damage to GI -> diarrhea, vomiting, etc. (Cholera, S. food poisoning, bacterial dystentery)
Neurotoxins – inhibit normal NT flow (Tetanus, Botulinum)

16. What is endotoxin? How does it affect humans?
Made by G(-) cells, is the LPS in the outer membrane. Once ingested by phagocytes, LPS is relased, stimulating cell to release cytokine IL-1, which reaches hypothalamus. Resets the “thermostat”, h-thal. Releases prostaglandins to initiate the fever response (vasodilation, vasopermeability, high temp.). Can lead to shock due to decrease in BP from vasodilation.

17. How do the following help bacteria evade the immune system: antigenic variation and inactivation of antibodies or complement?
AV – evade immune system’s antibodies
Inactivation – cascade/signaling system is disrupted

18. What are cross-reactive antibodies? How are they involved in damage to host cells?
Antibodies produced in response to an antigen, that undergo slight variation in the final differentiation process, that are similar enough to our own proteins to elicit an inflammatory response against our own tissues. Strep throat -> rheumatic fever, glomerulonephritis. Heart valves & strep. Antibiotics are prescribed with Strep. Infections not to help clear up the infection (which will subside in a few days), but to prevent the formation of antibodies that could attack our own cells.

19. What are superantigens? How are they involved in damage to host cells?
Antigens that are repeating polysaccharide units, stimulate non-T-cell-specific activation of the immune system, large cytokine release -> shock. Can get out of hand quickly, lead to death. Toxic shock syndrome (S. aureus).

Chapter 20 - Antibacterial Agents

1. Briefly describe the history of the antibacterial agents Protosil (sulfanilamide) and penicillin.
Protosil (sulfas) – 1935, used first in mice to treat systemic strep. Protosil is cleaved in the body to produce sulfanilamide, the active agent.
Penicillin – Alexander Fleming – Penicillium mold prevented bacterial growth on a plate.

2. Are all antibacterial agents antibiotics? Why or why not?
No – antibiotics are, by definition, made by other microorganisms. Some antibacterial agents, like the sulfa drugs, are made in the lab.

3. Describe the property of selective toxicity. Why is this an important property of antibacterial agents?
Selective toxicity means that the drug is selectively harmful toward the pathogen, and not our own cells. This is important because we want to maximize damage to pathogens while minimizing damage to our cells.

4. What is the difference between broad-spectrum and narrow-spectrum drugs? Under what conditions would each type of drug be used?
Broad – affects all, used when ID in unknown
Narrow – affects some, used when ID known, to protect NF

5. List the various targets of antimicrobial drugs and give which types of drugs have each type of target. (Those listed in Figure 20-1 and those discussed in class).

6. What are Beta-lactams? What do they do to kill bacterial cells?
Β-lactams are rings in the structure of antibiotics in the penicillin and cephalosporin families. They inactivate bacterial enzymes used in the synthesis of peptidoglycan. Without p-glycan, the cells cannot replicate.

7. What would be a problem with drugs used to fight fungal infections?
How about those used to fight viral infections?
Fungal – harder to crate drugs with selective toxicity as fungi are eukaryotic cells. More in common structurally, so harder to target.
Viruses – spend little time outside of host cells, hard to detect and target. Don’t carry out metabolism, so not “cell” processes to target.

8. List and describe the mechanisms of antibiotic resistance. What are beta-lactamases?
Destroy the drug (lactamases)
Altering drug target site
Increase drug elimination from cell, host
Alter permeability to drug (more impermeable)
β-lactamases are enzymes that break the β-lactam ring of antibiotics in the penicillin and cephalosporin families.

9. How is resistance to a drug acquired?
Begins with spontaneous mutation, and spreads through plasmid transfer (pili, phage conversion).

10. What human practices lead to antibiotic resistance in bacteria?
Overuse of antibiotics
Use by immunosuppressed individuals
Patient noncompliance
Animal feed

I saw this sign today as I walked up from the Hart toward the MC. There have been quite a few problems recently at crosswalks (both drivers not paying attention and pedestrians wandering all over the place). The school has been working with the city to try to remedy this (including drumroll..... fixing the crosswalk signals on 2nd South!! I thought I would never live to see the day! Especially the way the cars barrel through that intersection).

I guess this sign is one of the other ways they are increasing awareness. I read it as I walked by, thought about it while walking, started to laugh nearly out loud, and turned around to take a picture. "Use crosswalks!" "Share the Road!" But it's the caption at the bottom that gets me "think of the impact you can make". Um... I thought the idea was to NOT make an impact.

Hehe.

It's Saturday!!

I was so excited to wake up this morning and to not have to be anywhere any time soon. It's nice. I spent the night at Katie's again, and am convinced that she has the Best Couch in the World. Really! Today was the first day since Wednesday that I haven't woken up with a migraine (which is weird, because I really haven't gotten them lately at all - the last one before this week was on tour with the Symphony Band in April). So, I am giving credit to the couch. :) I met Katie at her work last night so we could head over to her apartment together. She works at Hogi Yogi, which is a bit of a Utah-Idaho institution... but is basically a fast-food type place, but a little higher up than McDonald's. Anyway, they had some drama there last night - someone graffitied one of their booths. They have security cameras, though, so they'll be able to figure out who did it (only a few people sat at that bench last night). We were talking about it afterward, and just thought it was a little funny - the graffiti was a gang tag (which in and of itself isn't funny), but... a gang tag in Rexburg? Borderline hilarious. What, are they having drug territory wars? It was probably just some 14-year-old who was trying to be cool. Anyway.

I've been thinking of what to do next year... I know I'll be home for a while, but I'm trying to figure out a more long-term plan. I still think that med school is the way to go for me, but I just may have to take a different route to get there. So I'm starting to think of what I need to do to make myself a stronger applicant for next year, and also thinking about possible master's programs. It's a little hard, because I don't have a strong interest in research (last summer cured me of that, haha... sigh), but many programs focus on that. I really just want something that will help me gain a better understanding and perspective in medicine and prepare me for med school. I started thinking about bioethics, which I think would be really neat. The only catch is that there seems to be only one program in all of Canada, at the U of T. And Toronto is a nice city, but... I guess it would just be nice to have a few more options. There are some online master's programs, but I'm pretty wary of those and how useful they would prove to be in further studies and jobs. Another program is a master's of public health, which would be really cool. BYU (Provo) has a great MPH program, and for part of it you get to work in an underdeveloped area of the country or the world and implement a program that you help design (eg. stop smoking program, patient education programs, etc). Which I think would be an A-M-A-Z-I-N-G opportunity! But let's be honest... I'm not sure I could handle Provo! Haha... I guess I'll have to think about things a bit more.

Sometimes I just want to forget about it all and go to law school instead. Sometimes I want to forget it all and be a bum on the street, but of those two options, I'm pretty sure my parents would disapprove of the latter.

Or maybe the former. ;)

So things have settled down a little... the two roommates who were kicked finally *moved* out this week. It was pretty tense until they did, but things have been ok since then. And by "ok", what I really mean is "no one is openly hostile". Which is a nice change, but... still a far cry from what would be nice. Anyway, I am glad things are a little better.

I had a good day in the ceramics studio, I was able to get some work done and am really happy with hoe it turned out. We did a Raku firing in class today, which was a lot of fun. With Raku, when the pieces are fired and really hot, you pull them out of the kiln and then set them in bins that are full of sawdust, newspaper, and other combustibles. The pieces are so hot that they ignite the material, and the ash produced gives the piece a cool finish. I'm hoping to Raku fire a piece next week. The ones done today were really beautiful. The only drawback is that the pieces don't get hot enough to vitrify, and they remain porous, so you can't use them to hold food or water. But I think I'll still give it a shot. I'm hoping to find a ceramics studio in Winnipeg so I can keep up with it after graduation.

Untitled 4, 2009.

I think sometimes things get worse before they get better.

This appears to be one of those times.

But my religion professor (Brother Ferguson) shared something today that I thought was applicable... "The difficulties proceeding the decision are evidence of the correctness of that decision". It's a cruel fact of life that doing the right things can often times land you in more hot water than doing the wrong things. But, at the end of the day (okay, actually wayyy more long-term than just one day), the frustrations and difficulties of life will seem small compared with the person you have become through them. It's just the going through part that stinks. ;)

I'll be at Katie's tonight.

Ta-da!

My first finished piece!

The glaze on the outside is blueish, and the inside glaze is sort of a rusty colour. They're both speckly, which is fun. I'm rather proud of it. It was a little harder than I thought it would be to get the glaze to stay where I put it, so it ran around a bit, but it turned out looking neat anyway. It definitely takes a while to get a piece from start to finish - shaping can a take a while, depending on what you are making and if you are adding any texture details, and then it needs to dry. Once dry, it goes in for bisque firing, and then you can put a glaze on it. It is then fired a second time (and at a much higher temperature), and this actually turns the glaze and some of the minerals in the clay to glass. After the second firing, the bottom of the piece (that didn't get glazed) needs to be smoothed out, since the clay gets really rough. You can't put glaze all the way to the bototm egde of the piece because it would run down off the piece and onto the kiln, and when it cools = HUGE MESS.

So I glazed another piece today, and hopefully it will be out of the kiln soon (firing takes a couple days). I realized that I need to get working on things for this class- our final is to present 6 finished pieces (good ones... haha), and since it takes a little while to get it all done, I really should get moving on it. I haven't glazed my bird's nest yet - it got a crack in it that I need to fix, and it's going to take a large chunk of time to do that. So maybe this Saturday will be a ceramics day... :)

This is a little late...

So, my amazing sister-in-law Jess tagged me in a post of hers in February, and because I am kind of a blog slacker sometimes (ok, most times, excepting random bursts of creative energy like I've had this week), I haven't done it yet. Sorry! I'm supposed to write six random things about myself and then tag others to do the same. So... here goes!

1. I am currently eating a grape popsicle. The popsicle stick has a joke on it - it asks you a riddle question on the "dry" end, and then when you finish the popsicle, you get the answer. They're always really lame, but I like them anyway, and try to guess what the answer will be. Today's joke is "What has wheel and a trunk but no engine?" I'm going with "An elephant on roller skates".

2. I had the biggest group session at work EVER today. I had 7 students at once, and while it was different from what I was used to, and I had to modify my teaching style a bit, it was really good and we got through a lot of material. The students were able to feed off each other and quiz each other a lot, which was great. The best part of work is helping things "click", and that happened a lot today, so it was a good day.

3. Sometimes I get really motivated and excited about cooking and trying new recipes, but I'm gradually coming to admit and accept that invariably, when I get to the store with my beautiful list of necessary ingredients, it all seems too daunting and expensive, and I start thinking of everything adding up and all the chopping and measuring and cooking involved, all for a recipe that may not even be tasty. Eventually I give up and buy bread, peanut butter, and noodles. Or, worse yet, I buy half the ingredients and let them sit in my pantry, unused and unloved. I need to figure out what to do with that curry mix....

4. I rarely read the school newspaper because it makes me too angry. We're in college, people! Grammar should not be a complicated issue! And WHERE was the editor?!?! The writing also tends to be very poor in content. Last week there was an article about vegetarianism (anti-veg), and the writer used the President of the Cattleman's Association as her main source. Um... I'm sure he's a nice guy, but I'm also sure there *may* be some bias. Just sayin. I would have written a letter to the editor, but I was too irritated to be articulate. Haha.

5. I love white boards. I carry dry erase markers in my backpack! I justify it by saying that I use them for work (you know, so the students can draw things out on the boards...), but let's be honest... I use them more than they do. They're just perfect for drawing out cell processes and chemical pathways! And they come in such pretty colours.

6. I actually like all my classes this semester. Even if I don't enjoy every minute of them, or all the work I have to do for them, I am learning about lots of different things (Music, Ceramics, Medical Microbiology, Doctrine and Covenants, and Political Science), and it's all interesting. I think the trick is that I feel like they can each apply to or contribute to my life in some way, even if I have to get a little creative in establishing the connection sometimes... haha.

I guess that's it... and now, I'm going to tag... Teags, Romy, and Theresa. But no worries if you take a month to reply like I did. :)

Oh, and the answer to the riddle... "An elephant on rollerblades"!
I know, I know... I was off on the roller skates/rollerblades thing (kids these days... always having the new toys...) but I'm still counting it. Which means... I'm awesome!!! Either that, or I have eaten far too many of those things and now just know the type of humour they use. That's a scary thought.

Ok, one more update...

I came home last night after going to the grocery store (thanks, Judy Kay!). I was pretty tired, so I just had a nice warm bath and went to bed. I got up this morning and it was pretty quiet, but I was ok with that. I needed to make a phone call to another girl in our ward, so I went to got our ward directory. I discovered that in the time I was gone, someone had drawn horns and a tail on our Bishop's picture. Seriously. It irks me on so many levels! First, yes, this is the maturity level I'm dealing with. Second - he's the Bishop! Way to sustain church leaders... sigh.
Two of my roommates (the two I wrote about yesterday) came home from meetings this morning (I think, I didn't get the details). They gave the news: kicked out of school, and have to be gone by the end of the week. I feel as though I should feel at least a little sad for them, but I don't. They were given so many chances to fix things and change, but all they could see was someone "telling them how to run their life". I guess that's the sad part.

Anyway, I'm sure I'll sort my feelings out on this sooner or later and then be more articulate about it, but until then...

I'll probably be at Katie's house.
