XLD Agar is used for the isolation and differentiation of enteric pathogens in a laboratory setting. XLD Agar is not intended for use in the diagnosis of disease or other conditions in humans. Conforms to Harmonized USP/EP/JP Requirements.
XL (Xylose Lysine) Agar Base was developed by Taylor for isolating and differentiating Gram-negative enteric bacilli. XL Agar Base was supplemented with sodium thiosulfate, ferric ammonium citrate, and sodium deoxycholate to develop a more selective medium, XLD Agar.
XLD Agar was developed principally for isolating Shigella spp. and Providencia spp., and shown to be an effective differential media.
