MCBRIDE LISTERIA AGAR BASE

The disease listeriosis is a frequent cause of abortions in cattle and sheep. In human, symptoms are manifested as septicemia, encephalitis and circulatory monocytosis. Listeria multiplies over a wide range of temperatures, from 3?C to 45?C, and over a pH range of 5.0 to 9.6. It also survives in food products with pH levels outside these parameters. Because of these properties, Listeria survives the various food processing techniques. McBride Listeria Agar, recommended by APHA is used for isolating Listeria from clinical specimens and foodstuffs including raw milk. This medium helps in the detection of low numbers of L. monocytogenes present in food samples.
