LISTERIA OXFORD MEDIUM BASE, MODIFIED

Description

Listeria monocytogenes is the only species of the genus Listeria that is important as a human pathogen. Listeria seeligeri, Listeria welshimeri and Listeria ivanovii have been related with animal diseases. In any case, all the species are pathogenic between the ovine and bovine cattle. Positive diagnosis of listeriosis can be obtained only by the isolation and cultivation of the responsible bacteria from blood or CSF samples of the affected organisms. Listeria Oxford Medium Base is based on the formulation described by Curtis et al for isolation of L. monocytogenes from clinical and food specimens.
