A six-month-old infant is brought into the ER. The mother tells the physicians that the infant became flaccid after the mother prepared some honeyed milk. What would you do in this situation to save the baby?

The infant contracted botulism from the honey. I would immediately inject the infant with botulism immune globulin, and possibly feed them using IV fluids.

Correct, your turn.

Here is another fun one I have used on a Microbe Mission exam:
The following illustration is of a common, human infectious agent. Answer the following questions about it:
1. What is it?
2. What are two ways to test for an active infection (one is invasive, one is not)?
1. I believe it is Helicobacter Pylori, one of the causes of peptic ulcers.
2. I'm kind of grasping here, but: 1) Swabbing the stomach lining and 2) Using an endoscope maybe?
Also, ffffurious can post the next question, since they got whythelongface's right.

ID is correct but part 2 is only partially correct (endoscope is the invasive method).
Also, I was just posting tough questions to help everyone out. As a coach, I wasn't going to answer any questions posted here because it's not meant to help me.

It looks like vibrio cholerae to me. Dunno how to test for it, though I know the symptoms - rice -porridge diarrhea, etc. Maybe test the stool for cholera toxin and excess ionic concentrations?

Edit: rip, did not look at the mucus part, assumed it was just basic.

The shape in the picture is slightly undefined. Specially, the bacteria in this question is a spiral whereas V. cholerae is comma shaped.

The problem is, the bacteria in the picture does look comma-shaped, and it has those nice lophotrichous flagella, which makes it look like V. cholerae.
Obviously, upon closer examination, this is the stomach mucus lining. I didn't see the mucus part and assumed that the optimal growth pH defined the intestinal membrane - which is wrong too, the intestines would be far more basic than 5-6.
To test for ulcers, while not using an endoscopy - I'm guessing you meant the urea breath test as the non-invasive method?
