I thought I would post a question in here because I love this event. I used this question as a tie-breaker last year on a Microbe Mission exam. Enjoy!

What type (genus, species, subtype) of bacteria is shown here and what is it doing?

It looks like some bacteria, no idea what kind, is performing binary fission, but that's probably not it.

1. It looks like bacteria from the Genus Salmonella, not too sure about species and subtype. 2. It might be infecting the host.

It is bacteria. It is not actively performing fission. Good guess though!

Good analysis but incorrect genus. The genus is commonly know- but not Salmonella. I will tell you that it is infecting the host but the structure that it is forming is indicative to what genus/species it is and what it's doing.

Here is a hint. Although this image is not from the kidney, a severe infection of this can cause kidney damage/failure.

1. Enterohemorrhagic Escherichia coli (EHEC) 2. The bacteria are attaching to the intestinal epithelium.

Correct! Follow up question- what type of toxin does this type of bacteria produce?
