Staphylococcus

Genus of Gram-positive bacteria

Staphylococcus, from Ancient Greek σταφυλή (staphulḗ), meaning "bunch of grapes", and κόκκος (kókkos), meaning "kernel" or "Kermes", is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters. Staphylococcus species are facultative anaerobic organisms (capable of growth both aerobically and anaerobically).
