L.MONO SELECTIVE AGAR BASE

Description

The genus Listeria constitutes Listeria monocytogenes, Listeria ivanovii, Listeria seeligeri, Listeria welshimerii, Listeria innocua, Listeria grayi, Listeria murrayi and Listeria denitrificans. Among these, L. monocytogenes and L. ivanovii are associated with diseases in humans. The pathogenicity of L. ivanovii is uncertain. L. monocytogenes is found in a wide variety of habitats, including the normal microflora of healthy ruminants, gastrointestinal tract of asymptomatic humans and environmental sources including river water, sewage, soil, silage, fertilizers and decaying vegetation. LM Selective Agar Base is recommended for the direct presumptive enumeration of Listeria species especially Listeria monocytogenes from meat, poultry, dairy products and environmental samples using membrane filtration technique.
