BROMO CRESOL PURPLE AGAR W/O CARBOHYDRATE

Description

Enteropathogens are well known to be transmitted via contaminated food or water. They are often implicated in major foodborne outbreaks worldwide. The common implications are gastroenteritis, vomiting, diarrhea, nausea, malaise, fever in humans. Enterotoxins produced by members of Enterobacteriaceae are important in the pathogenesis. Salmonella causes enteric fevers and food poisoning in humans. The most frequent sources of Salmonella food poisoning are poultry, meat, milk and milk products. Even salads and uncooked vegetables may cause infection if contaminated. Similarly, Vibrio can enter the human host through contaminated foods or water, causing intestinal infections and Cholera. Bromo Cresol Purple Agar w/Lactose is a non-inhibitory medium used for detection and isolation of coliforms and in differential study based on lactose fermentation. All coliforms ferment lactose with acid and gas production. The lactose fermenting organism changes the colour of the medium from purple to yellow.
