Document Summary
The microbe population (what kind and how much of each) in a particular region/area as determined by dna identification processes: techniques e. g. pcr, microbiota. The population of microbes in an area. Different from microbiome it is not determined by dna identification processes: to find if there is an infective bacteria (2 ways) Use pcr: discusses various microbiomes in/on body, what they discovered. Area they thought were sterile actually have their own bacterial community: commensal bacteria. Bacteria that live on/in human body that either help protect it or don"t do anything at all. Some can become pathogenic: pathogenic be able to infect, known as opportunistic pathogens, e. g. Pseudomonas (genus name) aeaginosa: mostly on skin (also mouth, if get into blood stream or internal organs. Changes its genetics and create toxins: no tissue is sterile . Tends to have a lot of diversity. Also have a core set of microbes (shared amongst everybody) but the rest can vary (diversity)
