PSB BROTH MODIFIED (ISO 1994, ISO/DIS 10273)

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. PSB Broth Base is recommended by APHA for the primary enrichment of Yersinia species. PSB Broth Modified is a modification of PSB Broth recommended by ISO Committee. Supplementation of phosphate buffer with sorbitol and bile salts appears to be better for cold enrichment.
