Staphylococcus hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of spherical cells in clusters. It occurs very commonly as a harmless commensal on human and animal skin. However, like many other coagulase-negative staphylococci, S. hominis may occasionally cause infection in patients whose immune system is compromised, for example by chemotherapy or predisposing illness. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

Laboratory identification of S. hominis is not difficult. It is one of only two species of Staphylococcus that 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. Deferoxamine, otherwise known as desferrioxamine or desferal, is a chelating agent used to remove excess iron from the body. ... Trehalose also known as mycose is a 1-alpha (disaccharide) sugar found extensively but not abundantly in nature. ...

Colonies of S. hominis are small, usually 1-2 mm in diameter after 24 hours' incubation at 35 degrees Celsius, and white or tan in colour. Occasional strains are resistant to Novobiocin and may be confused with other resistant species (eg. Staphylococcus saprophyticus.) The degree Celsius (°C or ℃ (Unicode 0x2103)) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701–1744), who first proposed a similar system in 1742. ... Staphylococcus saprophyticus is a coagulase-negative species of Staphylococcus which is often implicated in urinary tract infection. ...
