Staphylococcus xylosus

Staphylococcus xylosus is a member of the genus Staphylococcus, a genus of Gram-positive bacteria that form clusters of cells. Like many other staphylococci, it is coagulase-negative and exists as a commensal on the skin of humans and animals and in the environment. It appears to be far more common in animals than in humans. S. xylosus has very occasionally been identified as a cause of human infection, but in some it may have been misidentified.

In common with S. saprophyticus and several other species, S. xylosus is resistant to the antibiotic Novobiocin, Fleroxacin susceptible, Teicoplanin susceptible, Penicillin susceptible, Methicillin susceptible,Tetracycline susceptible,Erythromycin resistant. It is highly active biochemically, producing acid from a wide variety of carbohydrates.

Aerobic acid production from D-(+)-galactose, D-(+)-mannose, D-(+)-mannitol, maltose, & lactose(6) Caseinolytic & gelatinase activities. Produces slime but not capsules and this ability lost upon subculture Cell wall peptidoglycan similar to L-Lys-Gly3-5, L-Ser0.6-1.5 type found in predominately human species
