YERSINIA ISOLATION AGAR *

Yersinia is a gram-negative bacillus that is usually nitrate reductase-positive, fermentative, oxidase-negative and facultative with respect to oxygen requirement. Yersinia is usually urease-positive and motile at 25?C but not at 35?C. It is relatively sensitive to acidic conditions; therefore acid foods and fermented products should be analyzed promptly. A variety of enrichment methods have been described for recovery of Yersinia enterocolitica from foods. Highly selective enteric plating media, such as SS Agar have been used for isolation of Yersinia. Yersinia Isolation Agar has been developed for selective isolation of Yersinia species and preliminary differentiation of Y. enterocolitica from human and animal intestinal contents. The medium is recommended by the ISO Committee for identification of Yersinia species from foods.
