Patient: 6 month old boy
Symptoms: poor feeding, irratibility, diffuse skin erythema, epidermis coming off easily with gentle pressure

Diagnose the condition (species + any relevant information) and identify the cause (antigen? cell lysis? endo/exotoxin?) of the symptoms.
I didn’t think anyone would actually test on this lol. I believe it’s SSSS and it’s caused by staphylococcus, or in the case of our list MRSA. It produces an exotoxin that causes these symptoms.
Hopefully I’m not entirely wrong :D

Are you B division? Because MIT/SOUP diagnoses were pretty hard. Diffuse skin erythema is characteristic of SSSS, but make sure you don't confuse it with toxic shock syndrome or TS-like syndrome (caused by S. pyogenes).

Yea I’m div B. Usually the tests are not to the level of detail to test things like this

I guess I’ll just post a question
Image
1. What domain is this organism from
2. What is this specific individuals effect on human life
3. What is significant about its structure/appearance

Edit: Sorry for double post :?

1. Bacteria
2. Produces antibiotics as secondary metabolites
3. They are filamentous (resemble fungi) in that they form hyphae and reproduce through spores

Q: A 60-year old male has been HIV positive for more than 5 years. The HIV strains from his blood have a significant increase in pol gene mutations over the past year. He has been on the same course of antiretroviral therapy over this 5 year period. What is a possible cause of this finding?

Sorry to divert the thread, but how did you know the answers to this? Like, what gave away all of those details? I wouldn’t even know how to approach that.

ID is super important. Not so much nationals, but PA states has a ton of this stuff. Streptomyces produces more than half of human antibiotics (and the blue color is from one of the types of antibiotics they secrete), and it is the major type of filamentous bacteria (so be able recognize this type of morphology).

When you realize that the person from Troy who won Microbes last year won gold at International Biology Olympiad, you also realize that knowing everything on Wikipedia isn't enough.

1. Is that where streptomycin came from?
2. That's what Campbell, Tortorra, Alberts, and Lehninger is for

You’ve effectively killed the thread :P . Maybe some help?

Agreed. I’ll take a (bad) guess:
The virus has gained resistance to the ART via the natural selection of a beneficial mutation.
