I challenge this
Disinfection does not always get rid of microbes that cause disease. Like sanitization, disinfection also serves primarily to reduce, not completely eliminate, pathogens.

Though they both are similar in how they do not kill all of the microbes, sanitization is still different, as it's main goal is to lower the amount of harmful microbes to match with public safety standards. In general, disinfectants tend to kill more microbes that could be considered harmful. They are very close in definition, but still not the same

Ugh, formatting is being so weird right now

Just a pedantic note: the name of an organism is only ever italicized if it's part of the Scientific name. So, that would be Candida albicans, or simply C. albicans. "Candida yeast" would not be correct, nor would Dengue Fever.

A small note, I'm sure, and I probably sound really annoying for bringing that up, but it's the second time that I've seen this on this thread.

Agreed. Also, instead of referring to prions as a “microbe” the phrases “microbial agent” or “causative agent” (of a disease) are more correct.

Looks all correct, and for 3c my notes say "Aedes aegyptii". Your turn!

Aedes aegypti is the name of the mosquito that transmits Dengue. Break bone fever is a common name due to the joint pain associated with Dengue.

Ah, okay. Anyway, let's move on. Nano1llus10n may post a question.

Here’s a question that I’ve been trying to figure out lately:

The presence of cardiolipins and porins are separately cited as evidence of endosymbiosis. Why are cardiolipins found on the inner mitochondrial membrane, but porins on the outer mitochondrial membrane, if both are also found in bacterial cell membranes?

I must admit I don’t know the answer but I hope that someone does.

Mitochondria stain gram-negative/gram-intermediate and are thought to be evolved from G- bacteria (Rickettsia); porins are found only on the G- outer membrane (inner membrane has different proteins like PTS and ABC) while cardiolipins are found only in the inner cytoplasmic membrane. A quick PubMed search tells me that cardiolipin domains may be involved in bacterial cell division? IDK how you would explain why each is found where other than pointing to evolution.

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.

Hmmm, when I posted that question I thought that BOTH cardiolipins and porins were found on the bacterial cytoplasmic membrane (which would make it weird that the former are found in the outer mitochondrial membrane and the latter on the inner — the focus of my question) but actually what you posted is correct. My bad.

I have a few guesses for your question, but they’re just guesses so I won’t bother posting them. I’ll be interested in the answer though.
