STAPHYLOCOCCUS

Staphylococcus is a genus of spherical nonmotile Gram-positive bacteria that occur widely as saprophytes or parasites, the cells occurring in grape-like clusters. Many species inhabit the skin and mucous membranes, and some cause disease in humans and animals. Staphylococcus aureus infection can lead to boils and abscesses in humans; this species also produces toxins that irritate the gastrointestinal tract and result in staphylococcal food poisoning.
