If you expose a amoeba protozoan to an antibiotic would it kill it? I'm having a hard time fuguring this out.

Some may die at really high concentration, but usually not.

search the web for how different antibiotics affect bacteria and why they wouldn't affect the eukaryotic cell. It's easy-to-get info.

Ren, that really depends on the antibiotic... Look at the type of antibiotic, the mode of action and look at the structure of your amoeba.. Some antibiotics like penicillin and its derivatives, for example, target cell wall synthesis. Does your amoeba synthesize CW? Or some targets DNA and RNA synthesis but it has to penetrate the CM for it to work. There are very complex interactions of antibiotics and organisms and still a lot more if you are going to use those antibiotics to treat infected people. You still have to consider toxicity, accumulation of antibiotic in area of infection, patient sensitivity, etc...

Hint: If you take an antibiotic, does it kill your bodies cells too?
A: Nope.
Think about what kills the bacteria.
Would that affect a protozoan?

Well thats not completely accurate. Antibiotics toxicity is a big deal

Antibiotic means substance that inhibits or kills microorganisms (even though lately this term is primarily used to describe anti-bacterial agents). Antibiotics specific to ameba are Amebicides, while those that kill bacteria are Bacteriocides. Some antibiotics like Metronidazole are both...
