Abstract
Staphylococcus warneri is a member of the bacterial genus Staphylococcus, consisting of Gram-positive bacteria with spherical cells appearing in clusters. It is catalase-positive, oxidase-negative, and coagulase-negative, and is a common commensal organism found as part of the skin flora on humans and animals. Like other coagulase-negative staphylococci, S. warneri rarely causes disease, but may occasionally cause infection in patients whose immune system is compromised.
Clinical importance
Staphylococcus warneri has been suggested as a cause of spontaneous abortion in cattle and humans.Barigye R, Schaan L, Gibbs PS, Schamber E, Dyer, NW (2007).

Invest. 19(6): 694-696 It has been associated with vertebral discitis,Announ N., Mattei J., Jaoua S., Fenollar F., Sati H., Chagnaud C., Roudier J., Guis S.

Infect. 52(1):e15-18 Similar to other coagulase-negative staphylococci, the presence of S. warneri in blood and cerebrospinal fluid cultures can also represent contamination rather than a true infection. It has been suggested as the cause of a case of meningoencephalitis in a dog.Espino L, Bérmudez R, Fidalgo LE, González A, Miño N, Quiroga MI.

Identification
Colonies of S. warneri on trypticase soy agar are usually beige, tan, or yellow, sometimes with an orange rim and about 2–4 mm in diameter after 48 hours' incubation at 35 °C. Optimal growth temperature is 30-40 °C.
