Skin flora is usually non-pathogenic, and either commensal (are not harmful to their host) or mutualistic (offer a benefit). The benefits bacteria can offer include preventing transient pathogenic organisms from colonizing the skin surface, either by competing for nutrients, secreting chemicals against them, or stimulating the skin's immune ...
It is part of the skin flora of humans, [3] and its largest populations are usually found at the axillae, perineum, and inguinal areas. [4] S. haemolyticus also colonizes primates and domestic animals. [4] It is a well-known opportunistic pathogen, and is the second-most frequently isolated CoNS (S. epidermidis is the first). [5]

Its significance as a human pathogen was first described in 1938, [1] and in the early 1960s, GBS came to be recognized as a major cause of infections in newborns. [2] In most people, Streptococcus agalactiae is a harmless commensal bacterium that is part of the normal human microbiota colonizing the gastrointestinal and genitourinary tracts.
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.
