PSTA ENRICHMENT BROTH BASE

Yersinia enterocolitica are ubiquitous, being isolated frequently from soil, water, animals, and a variety of foods. They comprise a biochemically heterogeneous group that can grow at refrigeration temperatures. Y. enterocolitica has been detected in environmental and food sources, such as ponds, lakes, meats, ice cream, and milk. Yersinia species have the ability to grow at 4?C. Also they exhibit tolerance to dilute alkali. PSTA Enrichment Broth Base formulated in accordance with APHA, is recommended for secondary or selective enrichment of Y. enterocolitica. Secondary enrichment following primary enrichment is advantageous as it imparts higher selectivity, thereby increasing the chance of recovery or isolation of target organism.
