YERSINIA ENRICHMENT BROTH BASE *

Description

Yersinia enterocolitica and related species Yersinia intermedia, Yersinia frederiksenii and Yersinia kristensenii constitute a heterologous group of organisms, some of which are parasites and potential pathogens of humans and animals, while others are apparently saprophytic and free living in water, soil and vegetation. Y. enterocolitica has been isolated from humans with a variety of clinical symptoms ranging from mild gastroenteritis, appendicitis and terminal ileitis. Yersinia has also been isolated from many animal species throughout the world. Human infections probably occur from ingestion of contaminated food products or animal contact. Family and other small outbreaks suggest that person to person transmission occurs.
