HistoryThis species was described in 2003.[1] DescriptionThe cells are coccoid, Gram positive, catalase positive, oxidase positive with a diameter is 0·89–1·21 micrometres. Colonies reach 2–4 millimeters in diameter on P agar after 24 hours. Colonies are circular, smooth and glossy, without pigment. Growth is detected under anaerobic conditions at 15–36 °C and in 4% sodium chloride but not at 4 or 42 °C. The G+C content of the DNA is 41–42 mol%. It hydrolyses casein and gelatin but not Tween 80, starch, lecithin, aesculin or tyrosine. Alkaline and acid phosphatases are produced, nitrates are reduced. Acetoin, clumping factor and coagulase are not produced and activities of urease, haemolysis, arginine dihydrolase, arginine arylamidase, ornithine decarboxylase, beta-galactosidase, beta-glucuronidase, pyrrolidonyl arylamidase, esterase (C4), lipase (C14), Naphthol-AS-BI-phosphohydrolase, valine arylamidase, cystine arylamidase, alpha-galactosidase, N-acetyl-beta-glucosaminidase, alpha-mannosidase, alpha-fucosidase and esterase-lipase (C8) are negative. Acid is produced from D-fructose, D-glucose, maltose, D-mannitol and D-trehalose. Acid is not produced from arabinose, N-acetylglucosamine, D-cellobiose, D-galactose, or methyl alpha-D-glucoside, lactose, D-mannose, D-melibiose, melezitose, raffinose, ribose, D-salicin, D-sorbitol, sucrose, turanose, xylitol and xylose. It is resistant to novobiocin. Predominant fatty acids are iso-13 : 0, iso-15 : 0, anteiso-15:0, 16:1-omega-11c, iso-17:1-omega-10c and 18:1-omega-9c. EpidemiologyThis species was isolated from the skin of llamas (Lama glama). ClinicalThis species has not been associated with disease.
