Isolation and characteristics of Yersinia enterocolitica-like bacteria from meats. 1979

M O Hanna, and J C Stewart, and Z I Carpenter, and D L Zink, and C Vanderzant

Seventeen Yersinia enterocolitica-like isolates from vacuum-packaged beef and lamb are described. A majority of the isolates were motile at 25 degrees C but not at 36 degrees C, utilized citrate at 25 degrees C (delayed or negative at 36 degrees C) and produced acid from rhamnose, raffinose and melibiose. Increases in count of Y. enterocolitica occurred on raw beef stored at 0--1 degrees C over a 10-day period. No viable Y. enterocolitica were detected in beef roasts which were inoculated with about 3 x 10(6) cells/g and subsequently heated to a final internal temperature of 60--62 degrees C. Y. enterocolitica counts of inoculated beef steaks stored at 1--5 degrees C for 21--35 days were consistently higher in the more oxygen-permeable films than in vacuum packages. Colonies of Y. enterocolitica and related bacteria from meats produced shiny, enamel-black colonies on bismuth sulfite agar with plate incubation at 25 degrees C for 3--5 days.

D000362	Agar	A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
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.

D012756	Sheep	Any of the ruminant mammals with curved horns in the genus Ovis, family Bovidae. They possess lachrymal grooves and interdigital glands, which are absent in GOATS.	Ovis,Sheep, Dall,Dall Sheep,Ovis dalli
D015007	Yersinia	A genus of gram-negative, facultatively anaerobic rod- to coccobacillus-shaped bacteria that occurs in a broad spectrum of habitats.
