WESLEY BROTH BASE (as per APHA)

Description

Campylobacter jejuni is a gram-negative, rod-shaped curved bacterium commonly found in the intestines of poultry, cattle, swine, rodents, wild birds, cats and dogs. C. jejuni is recognized as a leading cause of acute bacterial gastroenteritis in humans due to eating the food of animal origin. C. jejuni is often isolated from patients with diarrhea at greater isolation rates than reported for Salmonella species. This organism does not grow below 30?C and is sensitive to normal atmospheric concentration of oxygen. Due to this reason, only small numbers of Campylobacters may be present in foods. Hence selective enrichment is needed to detect the few culturable cells of C. jejuni that may be present. C. jejuni survives best in foods held at refrigeration temperature but is highly susceptible to freezing conditions and also sensitive to sodium chloride. Wesley Broth is formulated as described by Wesley and recommended by APHA for selective enrichment of C. jejuni from poultry products.
