Deoxycholate Citrate Agar is used for the isolation and differentiation of Gram-negative enteric bacilli in a laboratory setting. Deoxycholate Citrate Agar is not intended for use in the diagnosis of disease or other conditions in humans.
Deoxycholate Citrate Agar is a modification of Deoxycholate Agar formulated by Leifson. His original formula, Deoxycholate Agar, was used for isolation of intestinal pathogens and enumeration of intestinal pathogens in milk and water. Deoxycholate Agar was an improvement over other media because citrates and sodium deoxycholate worked well as inhibitors.
Leifson modified the original medium by increasing the concentration of Sodium Citrate and Sodium Deoxycholate for improved recovery of Salmonella spp. and Shigella spp. Deoxycholate Citrate Agar effectively isolates intestinal pathogens by inhibiting coliforms and many Proteus spp. This medium is used to screen Salmonella spp. and Shigella spp. from samples.
