Staphylococcus caprae is a Gram-positive, coccus bacteria and a member of the genus Staphylococcus. S. caprae is coagulase-negative. It was originally isolated from goats (caprae means "of a goat"), but members of this species have also been isolated from human samples.

Staphylococcus caprae occurs as a commensal on human skin, but has also been implicated in infections of the bloodstream, urinary tract, bones, and joints. Because S. caprae is difficult to identify definitively in the laboratory,cite-ref-1[1] according to a study in 2014, the incidence of S. caprae in humans is under-reported.cite-ref-2[2]

It is a coagulase-negative, DNase-positive member of the genus Staphylococcus. Usually it is associated with goats. Since 1991, a few laboratories reported that they had isolated the organism from human clinical specimens.cite-ref-3[3] It is now an emerging microorganism in joint and bone infections in humans.cite-ref-4[4]

Staphylococcus caprae was first described in 1983 by Devisee et al. based on a strain isolated from goat milk. It can sometimes cause mastitis in the goats, and it is considered a commensal organism for the goats’ skin and mammary glands. It has been reported as a pathogen for humans acquired at hospitals, mostly in bone and joint infections.cite-ref-5[5] There have also been studies on S. caprae causing sepsis in clinical settings.cite-ref-6[6]
