[Identification of Listeria species in 167 kinds of foods].
Through preliminary identification of isolation of Listeria species in six types foods, which consisted of 167 kinds of foods, we found both S-form and R-form colonies were suspected colonies of Listeria species, and some of them were catalase-negative, urease-positive, methyl red(MR) negative and Voges-Proskauer(VP) negative. The results showed that S-form, catalase-positive, urease-negative, MR-positive and VP-positive colony should not be used as the strict criteria for the identification of Listeria.
