Homework Answers
Hello
Welcome to HomeworkLib study.
Mycoplasma species are the smallest prokaryotic microbial cell. They are signet ringed shaped bacteria. They are gram negative.
One of the characteristic feature of mycoplasma species is that they lack cell wall.
The mechanism of action of Penicillin or the other 
-lactam
antibiotics is that they inhibit the cell wall synthesis of the
bacteria.
But here the mycoplasma species does not have cell wall so the
penicillin or other -lactam
antibiotics can not inhibit their growth. So mycoplasma species
have natural resistance from them.
I hope my answer will be of some help to you.
Thanks

Explain why antibiotics have no effect on viruses. If this is the case, why then, when we go to the doctor, many of us insist on being treated for a virus? How are antibiotics being misused in our society? Explain the advantages, disadvantages, and dangers of overuse of antibiotics. Pull into the conversations your personal/professional experience, documentation found from other CREDIBLE sources, etc. Provide a concise, logical rationale for your opinions and cite your resources when appropriate.

Explain why the overprescription of antibiotics by doctors, or the overuse of everyday soaps containing antibiotics, can be a health risk. O The overuse of antibiotics or antibiotic soaps can be a health risk because the repeated exposure to antibiotics can damage human cells. When antibiotics are overused, the repeated exposure triggers mutations in the bacteria that result in resistance. Resistant bacteria will then survive and multiply, reducing the effectiveness of the antibiotic treatment in the future. When antibiotics are...
