D.C.L.S. AGAR

Description

Salmonella infection leads to salmonellosis, which ranges clinically from self-limited gastroenteritis (diarrhea, abdominal cramps and fever) to enteric fevers (including typhoid fever). Shigella species causes classical bacillary dysentery characterized by severe cramping abdominal pain and diarrhea with blood and mucus. D.C.L.S. Agar is a modification of Deoxycholate Citrate Agar of Leifson. It is a slightly selective and differential medium, which incorporates sucrose as an additional fermentable carbohydrate to differentiate lactose negative sucrose positive coliforms from Salmonella species The addition of sucrose to this medium increases its usefulness because non-pathogenic sucrose fermenting organisms like Proteus, Enterobacter, Klebsiella form red colonies. D.C.L.S. Agar is a moderately selective culture medium which also supports the growth of Vibrio species.
