Listeria monocytogenes isolates from bovine hides and carcasses (n = 812) were mainly of serogroup 1/2a. All strains were positive for internalin genes. Several isolates were resistant to oxacillin (72.2%) or clindamycin (37.0%). These findings indicate that L. monocytogenes of beef origin can be considered a public health concern.
从牛体和牛体组织(n = 812)中分离出的单核细胞增生李斯特菌主要为血清群 1/2a。所有菌株均对内毒素基因呈阳性。一些分离株对苯唑西林(72.2%)或克林霉素(37.0%)具有耐药性。这些发现表明,来自牛肉的单核细胞增生李斯特菌可能被视为公共卫生关注点。
