Webster et al. 1994 ; corrected by Trüper and De’ Clari 1998); synonym: Staphylococcus pulvereri Zakrzewska-Czerwinska et al. 1995.
Gram positive cocci, non-motile, non-sporing.
Colonies are opaque, yellow, sometimes with irregular margins. Facultatively
anaerobic – grow better aerobically, 37 ºC. Media: Trypticase Soy Yeast extract Agar ±
5% sheep blood, Mueller-Hinton agar, P agar.
Isolated from human clinical samples (urine), animals - calf (latin “vitulus”), horse, fish & meat products.
Resistant to novobiocin.
Unknown; potential nosocomial infections & food contaminant.
