Question

In a hospital, several patients became infected with a bacterium after surgery. The patients are not responding to antibiotics. By what type of disease are these patients likely infected, and why is it such a risk?

Answer 1

Most likely a bacterial infection.
Probably MRSA (Methicillin-resistant Staphylococcus aureus)
It's such a risk because it spreads easily in hospitals and sick patients are very sensitive.
On top of that it's hard to kill those bacteria because they're resistent to many antibiotics.

Answer 2

@thomaster thank you so much

Answer 3

recently there have been a few total resistant strains of E.coli and another one that I cant think of at the moment, which is a bit more scary, but I would go with MRSA as well--although the question is vague enough you could probably pick anything you wanted and be correct.
