CAL BROTH (CELLOBIOSE ARGININE LYSINE BROTH)

Yersinia enterocolitica is a significant invasive enteric pathogen belonging to the family Enterobacteriaceae, which causes several well-recognized diseases especially in younger persons and several uncommon post-infection syndrome. Enterocolitis caused by Y.enterocolitica is characterized by diarrhea, low fever and abdominal pain. CAL Broth used for selective isolation of Y.enterocolitica was originally formulated by Dudley and Shotts. CAL Broth is a differential medium as it differentiates Yersinia on the basis of cellobiose fermentation and lysine or arginine decarboxylation. As the organism is biochemically similar to other Enterobacteriaceae. CAL Broth is used for the enumeration of Y.enterocolitica from water and other liquid specimens.
