''Staphylococcus xylosus'' is a species of bacteria belonging to the genus ''Staphylococcus''. It is a Gram-positive bacterium that forms clusters of cells. Like most staphylococcal species, it is coagulase-negative and exists as a commensal on the skin of humans and animals and in the environment.〔Karl H. Schleifer and Wesley E. Kloos. Isolation and Characterization of Staphylococci from Human Skin I. Amended Descriptions of Staphylococcus epidermidis and Staphylococcus saprophyticus and Descriptions of Three New Species: ''Staphylococcus cohnii'', ''Staphylococcus haemolyticus'', and ''Staphylococcus xylosus''. Int J Syst Bacteriol January 1975 25:50-61; .〕 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 cases it may have been misidentified. ==Identification== ''S. xylosus'' is normally sensitive to fleroxacin, methicillin, penicillin, teicoplanin, tetracycline and resistant erythromycin and novobiocin. It is highly active biochemically, producing acid from a wide variety of carbohydrates. Acid and gas are produced from D-(+)-galactose, D-(+)-mannose, D-(+)-mannitol, maltose and lactose. Caseinolytic and gelatinase activities are normally present. It normally produces slime but not capsules. This ability is lost upon subculture. Its cell wall peptidoglycan is similar to the L-Lys-Gly3-5 L-Ser0.6-1.5 type found in predominately human species. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Staphylococcus xylosus」の詳細全文を読む スポンサード リンク
