question
Xylose Lysine Deoxycholate (XLD) Agar
answer
Isolation and differentiation of Salmonella and Shigella from other gram negative enteric bacilli
Salmonella: Red colonies with black center (Ferments xylose turn to yellow but also undergoes lysine decarboxylation so turn to red and H2S producer so black center)
Shigella: Colorless or red/ pink (Not fermenter so red/pink which is the color of the uninoculated media and not H2S producer so no black center)
E. coli: Yellow (Fermenter so yellow and not H2S producer so no black center)
