human microbiota
microorganisms can be found almost everywhere on earth. types of microorganisms include archaea, bacteria, eukaryotes, protists, fungi, and micro-plants. microbes are important in human culture and health in many ways, serving to ferment foods, treat sewage, produce fuel, enzymes and other bioactive compounds. they are essential tools in biology as model organisms and have been put to use in biological warfare and bioterrorism. they are a vital component of fertile soils. in the human body microorganisms make up the human microbiota including the essential gut flora. they are the pathogens responsible for many infectious diseases and as such are the target of hygiene measures. most microorganisms can reproduce rapidly, and bacteria are also able to freely exchange genes through conjugation, transformation and transduction, even between widely divergent species.
physiology
humans are colonized by many microorganisms; the traditional estimate is that the average human body is inhabited by ten times as many non-human cells as human cells, but more recent estimates have lowered that ratio to 3:1 or even to approximately the same number. some microorganisms that colonize humans are commensal, meaning they co-exist without harming humans; others have a mutualistic relationship with their human hosts. conversely, some non-pathogenic microorganisms can harm human hosts via the metabolites they produce, like trimethylamine, which the human body converts to trimethylamine n-oxide via fmo3-mediated oxidation. certain microorganisms perform tasks that are known to be useful to the human host but the role of most of them is not well understood. those that are expected to be present, and that under normal circumstances do not cause disease, are sometimes deemed "normal flora" or "normal microbiota".
