|---|
| Definition (CSP) | genus of gram positive, facultatively anaerobic, coccoid bacteria; organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. |
| Definition (MSH) | A genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals. |
| Definition (NCI) | A genus of nonmotile, nonspore-forming, aerobic to facultatively anaerobic bacteria containing Gram-positive, spherical cells, 0.5-1.5 microns in diameter, which divide in more than one plane to form irregular clusters. Coagulase-positive strains produce a variety of toxins and are therefore potentially pathogenic and may cause food poisoning. They are found on the skin, in skin glands, on the nasal and other mucous membranes of warm-blooded animals, and in various food products. The type species is Staphylococcus aureus. |
