Ontology: Staphylococcus aureus (C0038172)

Definition (NCI) A common bacterial species found especially on nasal mucous membrane and skin (hair follicles); bacterial species that produces exotoxins including those that cause toxic shock syndrome, with resulting skin rash, and renal, hepatic, and central nervous system disease, and an enterotoxin associated with food poisoning; it causes furunculosis, cellulitis, pyemia, pneumonia, osteomyelitis, endocarditis, suppuration of wounds, other infections; also a cause of infection in burn patients; humans are the chief reservoir.
Definition (NCI_CDISC) Any bacterial organism that can be assigned to the species Staphylococcus aureus.
Definition (MSH) Potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm-blooded animals. They may cause a wide range of infections and intoxications.
Definition (CSP) potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm blooded animals; may cause a wide range of infections and intoxications.
