However, many strains of S. aureus are metabiotic commensals, and are present on roughly 20 to 30% of the human population as part of the skin flora. [20] S. aureus also benefits from the variable ambient conditions created by the body's mucous membranes, and as such can be found in the oral and nasal cavities, as well as inside the ear canal.
Skin microflora can be commensals, mutualistic or pathogens. Often they can be all three depending upon the strength of the person's immune system. [3] Research upon the immune system in the gut and lungs has shown that microflora aids immunity development: however such research has only started upon whether this is the case with the skin. [3]
The Neisseriaceae are a family [2] of Pseudomonadota, within the Neisseriales order of Betaproteobacteria.While many organisms in the family are mammalian commensals or part of the normal flora, the genus Neisseria includes two important human pathogens, specifically those responsible for gonorrhea (caused by N. gonorrhoeae) and many cases of meningitis ("meningococcal meningitis", caused by N ...
The designation was conceived to accommodate a collection of gram-negative organisms currently representing 34 genera and 105 species, described as “specialized commensals, primarily and potential pathogens of vertebrates–mainly mammals and birds.” [9]
The body is continually exposed to many species of bacteria, including beneficial commensals, which grow on the skin and mucous membranes, and saprophytes, which grow mainly in the soil and in decaying matter. The blood and tissue fluids contain nutrients sufficient to sustain the growth of many bacteria.
Most bacteria are nonpathogenic. It can describe the presence of non-disease causing bacteria that normally reside on the surface of vertebrates and invertebrates as commensals. Some nonpathogenic microorganisms are commensals on and inside the body of animals and are called microbiota.
By modulating the moist, inner lining of some organs and body cavities and their specific immune defense mechanisms, skin commensals interact with infectious agents like pathogens. Sphingomyelin phosphodiesterase is the main driver in the S. epidermidis production of ceramides - a lipid that includes sphingosine and sphingosine-1-phosphate ...
