Answer #1

Bacterial strains that are grown in enriched culture without antibiotics can "lose" their plasmids.This might be because of the reason that in the enriched culture there is no selective agent i.e antibiotics against which the antibiotic resistant genes needs to be expressed.So, bacteria grow in colonies much more in enriched culture without antibiotics.Also,in the process of their division, as there is no selective agent, it might so happen that the resistant bacteria could lose their resistance genes(as they were devoid of a specific antibiotic for a specific time period)and lose their plasmids which is known as plamid loss.The plasmids finally become non existent in the bacterial population.

When a eukaryotic organism (such as a human) gets a bacterial infection, it can be treated with antibiotics. Antibiotics work by targeting prokaryotic cells without targeting eukaryotic cells. This is possible due to molecular differences between the two cell types that enable specific targeting of molecules in prokaryotic cells but not eukaryotic ones. The effects of different categories of antibiotics are listed below. For each one, explain how this would affect prokaryotic cells and why. Some antibiotics disable ribosome function....

Nearly all the antibiotics used to stop bacterial infections are natural compounds that come from microbes themselves. For example, penicillin is derived from a fungus, while vancomycin, the antibiotic used when bacteria are resistant to many other drugs, comes from a bacterium. Furthermore, although many antibiotics are chemically synthesized to resemble natural antibiotics, the “models” for them are natural products of microbes themselves. As more bacteria become resistant to traditional antibiotics, alternative drugs must be found. Recently, scientists discovered a...
