What else can I help you with?
Is the rapid development of bacteria resistant to penicillin an example of gradualism?
Punctuated equilibrium
Why some bacteria are resistant from penicillin?
Because its bigger and bigger is better ;)
Which semi-synthetic penicillin's creation was sparked by the discovery of Staphylococcus aureus bacteria resistant to penicillin?
Methicillin
What type of chemical will allow come bacteria to be resistant to many penicillin's?
penicillinase
Why the frequency of penicillin-resistant bacteria can change over time within the population?
its smaLL
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
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.
What impact did penicillin have on medicine?
It helps to kill bacteria. Therfore, it can treat many diseases. Although in modern time, bacteria are becoming resistant to antibiotics and penicillin is losing its effects.
Can penicillin treat tb bacteria?
No. TB is commonly resistant to numerous antibiotics. It's generally treated with a cocktail of antibiotics, none are Penicillin.
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.
Certain bacteria produce a chemical that makes them resistant to penicillin since these bacteria reproduce asexually they usually produce offspring that?
Carry the same resistance to penicillin as the parent bacteria. This resistance is usually conferred through genetic mutations or acquisition of resistance genes, allowing the offspring bacteria to withstand the effects of penicillin.
Gram negative bacteria are much more resistant to penicillin because?
Gram-negative bacteria are more resistant to penicillin due to the presence of an outer membrane that acts as a barrier, preventing the antibiotic from reaching its target (peptidoglycan layer). Additionally, gram-negative bacteria possess enzymes called beta-lactamases that can break down penicillin and render it ineffective. These mechanisms make it harder for penicillin to kill gram-negative bacteria compared to gram-positive bacteria.
