Himedia Deoxycholate Citrate Agar, HiVeg

This animal free medium is prepared as per the modified formula of Leifson. This medium is used for the isolation and maximum recovery of intestinal pathogens belonging to Salmonella and Shigella groups from foods. However, it is recommended to use less inhibitory medium when Shigella have to be isolated. The selectivity of this medium permits the use of fairly heavy inocula without danger of overgrowth of Shigella and Salmonella by other microflora. This medium is similar to Deoxycholate agar in comparison but is moderately more selective for enteric pathogens owing to increased concentrations of both citrate and Deoxycholate salts.
