    I'm pretty sure that wasn't the question. Amoxicillin is a borad spectrum anntibiotic so I would imagine is effective against both.

    just trying to help. but yeh i agree with you on the amoxicillin, i can also add that novobiocin is good against staphylococcus aureus but pseudomonas has resistance to it. again i'm not too sure what the question is

    it's a very specific one used for s aureus, just like isoniazid is specific to m tuberculosis. so the point is that amoxicillin is broad spectrum, whereas novobiocin isn't

    In all fairness it works on many mycobacterium. It's certainly a treatment for Mycobacterium Bovis, (not anymore due to laws preventing use of drugs for humans and animals) and I think it works against leprosy too (also a mycobacterium). it increases free radicals in mycobacterially in fected cells as i recall.
