Staphylococcus hominis
''Staphylococcus hominis'' is a coagulase-negative member of the bacterial genus ''Staphylococcus'', consisting of Gram-positive, spherical cells in clusters. It occurs very commonly as a harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour.〔http://www.sciencedaily.com/releases/2015/03/150330213947.htm〕 Like many other coagulase-negative staphylococci, ''S. hominis'' may occasionally cause infection in patients whose immune systems are compromised, for example by chemotherapy or predisposing illness.
==Description==
Colonies of ''S. hominis'' are small, usually 1–2 mm in diameter after 24 hours' incubation at 35 °C, and white or tan in colour. Occasionally, strains are resistant to novobiocin and may be confused with other resistant species (egg. ''S. saprophyticus'').
It is one of only two species of ''Staphylococcus'' to display sensitivity to desferrioxamine, the other being ''S. epidermidis''. Unlike ''S. epidermidis'', ''S. hominis'' produces acid from trehalose, so the two tests together serve to identify the species.
