Rating Newest Oldest. Best Answer: No, plasmids are not necessary to allow bacteira to survive .Plasmids are typically not strictly for survival and are only beneficial under certain conditions. The DNA necessary for bacterial life is usually in the chromosomal DNA. The plasmid DNA may confer benefits but the function of most plasmid DNA is currently unknown. Scientists have selected for plasmid free bacteria, and plasmid-free strains, especially E. coli, are available commercially.
Bacteria, viruses and fungi. If you think there must be a few of them inside your body as well, you're right: micro-organisms in your intestine, on the skin, in your mouth, nose and scattered throughout the body, outnumber your body cells by a wide margin. Most of them are bacteria and the rest are viruses and fungi.Normally, these bugs don't cause health problems, because your immune system keeps them in check. We coexisted for millions of years, simply because humans, through natural selection, have come out with the adequate defending mechanisms.ungal infections.
