DEOXYCHOLATE AGAR

Deoxycholate Agar is prepared as per the formulation by Leifson. This media is used for the isolation and maximum recovery of intestinal pathogens belonging to Salmonella and Shigella species. The selectivity of medium permits the use of fairly heavy inocula without danger of overgrowth of the Shigella and Salmonella by other micro-flora.
For the routine examination of stool and urine specimens, it is recommended that other media such as MacConkey Agar, Bismuth Sulphite Agar etc. be used in conjunction with this medium. It can also be used to streak specimen from Selenite Broth cultures. This is particularly recommended for the detection of Shigella and Salmonella in the examination of rectal swabs and faeces. These organisms produce colourless colonies on this medium.

for direct di?erential count of coliforms in dairy products and also for isolation of enteric pathogens from rectal swabs, faeces and other pathological specimens
