Abstract

One hundred and ten Listeria strains were recovered from 378 meat samples: L. monocytogenes (68 strains), L. innocua (45) and L. welshimeri (7). L. monocytogenes isolates mainly belonged to serogroup 1/2 (1/2: 23 strains; 1/2b: 1; 1/2c: 43; 4b: 1). These results contrast those observed for 355 human strains isolated during the same period in France where serovar 4b strains were largely predominant (66.5%). 45% of the strains were phage typable. These results underline the widespread occurrence of Listeria in meat products.

摘要

从378份肉类样本中分离出110株李斯特菌：单核细胞增生李斯特菌（68株）、无害李斯特菌（45株）和威氏李斯特菌（7株）。单核细胞增生李斯特菌分离株主要属于血清群1/2（1/2：23株；1/2b：1株；1/2c：43株；4b：1株）。这些结果与同期在法国分离出的355株人类菌株的观察结果形成对比，在法国血清型4b菌株占主导地位（66.5%）。45%的菌株可进行噬菌体分型。这些结果突显了李斯特菌在肉类产品中广泛存在。
