is penicillin biologically significant?

Question

if so what organs,tissues does it affect

Answer 1

doesn't affect human tissues
it act only on bacteria and prevent its cell wall synthesis

Answer 2

Penicillin is specific to a target within bacterial cell wall synthesis. The only human system it affects, and only in some people, is the immune system. Some people develop a negative allergic reaction which can cause anaphylactic shock, and potentially death.

Answer 3

penicillin is a substance that kills bacterias...and...funnz enough it is produced by them.if you watch a bacteria colony throughout a week...you will see it will die.because the substance that kills them is a side-product of theirs...junk...imagine living in a room full of junk....you cannot survive.
well...patients treated with penicillin (orally) usually have a hard time with it : it affects livercells, and kills the bacteria that we have in our stomach, digestive tract, and mouth, other parties down there...and those bacterias are "good" they "belong" to the organism.
using antibiotics can cause liverdamages, ulcer, yeast infections, candidosis, etc etc. if not used properly
