Which semi-synthetic penicillin's creation was sparked by the discovery of Staphylococcus aureus bacteria resistant to penicillin?
Methicillin
Certain bacteria produce a chemical that makes them resistant to penicillin since these bacteria reproduce asexually they usually produce offspring that?
survive exposure to penicillin
What type of chemical will allow come bacteria to be resistant to many penicillin's?
penicillinase
When the antibiotic penicillin was first introduced it was immediately effective in combating staphylococcus bacterial infections?
1. members of the original population of bacteria that were penicillin resistant survived and reproduced, creating a more resistant populationReasonsome members of the of the original staphylococcus population had a mutation that made them penicillin- resistant. they survived and reproduced and all their offspring were also resistant to penicillin, creating a more resistant population
Why the frequency of penicillin-resistant bacteria can change over time within the population?
its smaLL
What is MRS bacteria?
It is usually called MRSA: Methicillin-Resistant Staphylococcus Aureus. Methycillin is a version of penicillin that was developed to attack penicillin-resistant bacteria. MRSA can sometimes be treated with other common antibiotics like tetracyclines, e.g. doxycycline.

Can Staphylococcus grow in penicillin G?
It depends. Some bacteria, like Staphylococcus aureus, have become resistant to penicillin G. Not all species of Staphylococcus are resistant. Even some strains of Staphylococcus aureus are still susceptible to penicillin G.
