MacConkey Agar is the earliest selective and differential medium for cultivation of enteric microorganisms from a variety of clinical specimens. Subsequently MacConkey Agar and Broth have been recommended for use in microbiological examination of foodstuffs and for direct plating/inoculation of water samples for coliform counts. These media are also accepted by the Standard Methods for the Examination of Milk and Dairy Products and pharmaceutical preparations.
MacConkey Agar II w/o CV is the selective and differential medium. This media is specially designed to improve the inhibition of swarming Proteus species and to achieve more definitive differentiation of lactose fermenters. Lactose non-fermenting strains, such as Shigella and Salmonella are colourless and transparent and typically do not alter appearance of the medium. Yersinia enterocolitica may appear as small, non-lactose fermenting colonies after incubation at room temperature.
for selective isolation and differentiation of lactose fermenting and lactose non-fermenting enteric bacteria
