Pertaining to Staphylococcus spp.
- s. clumping test — used as a means of measuring the quantity of fibrinogen-split products in a sample of blood.
- equine s. dermatitis — see equine staphylococcal dermatitis.
- s. food poisoning — a disease of humans caused by enterotoxins elaborated by coagulase-positive Staphylococcus aureus of human origin. Dangerous foods for this disease are ham, dried milk and cold meats generally. Domestic animals appear not to be susceptible to the toxins but the disease is important to veterinarians because animal products, especially milk and chicken meat from animals in their care, may be the origin of this severe, often epidemic, gastroenteritis.
- s. granuloma — persistent, low-grade infection of connective tissue or muscle by Staphylococcus aureus causing the development of granulomas which can become very large, most commonly in the chest of the horse and the mammary gland of the sow. The granuloma is a dense mass of fibrous tissue containing a large number of small abscesses containing thick yellow pus containing granules of club colonies. Called also botryomycosis.
- s. hypersensitivity — see bacterial hypersensitivity.
- s. mastitis — of cows caused by S. aureus may be chronic, acute or peracute with gangrene of the quarter and sometimes death of the cow.
- s. phage lysate products — see staphage lysate.
- s. protein A — a cell-bound protein expressed by most strains of Staphyloccus intermedius recovered from dogs and cats.
- s. pyemia — see tick pyemia.
- s. septicemia — of lambs and less commonly other neonates; high mortality rate; umbilical infection the likely entry portal.
