Isolation and identification of Staphylococcus hyicus. 1977

L A Devriese

A selective medium for the isolation of Staphylococcus hyicus, with potassium thiocyanate as selective substance and the polysorbate 80 reaction as elective marker, was developed. The organism could be identified during the routine examination of samples derived from pigs, using 2 relatively simple tests: the slide coagulase (clumping factor) and the deoxyribonuclease plate reaction. The S hyicus was isolated from 54% of 684 samples collected from nares, external ears, and skin covering the nose of pigs not affected by exudative epidermatitis. Isolates from these animals did not appear to differ in pathogenic potentials from those obtained from lesions.

UI MeSH Term Description Entries
D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture
D004818 Epidermitis, Exudative, of Swine An acute generalized dermatitis of pigs which occurs from 5 to 35 days of age, characterized by sudden onset, with morbidity of 10 to 90% and mortality of 5 to 90%. The lesions are caused by Staphylococcus hyos but the bacterial agent is unable to penetrate the intact skin. Abrasions on the feet and legs or lacerations on the body frequently precede infection. In acute cases, a vesicular-type virus may be the predisposing factor. The causative organism is inhibited by most antibiotics.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013210 Staphylococcus 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 found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.
D013552 Swine Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
