The aims of this study were to determine the prevalence, characteristics and antimicrobial resistance of Listeria spp. isolated from bovine clinical mastitis in Iran. Listeria spp. were detected in 21/207 bovine mastitic milk samples from dairy farms in Iran, comprising L. monocytogenes (n=17), L. innocua (n=3) and L. ivanovii (n=1). L. monocytogenes isolates were grouped into serogroups '4b, 4d, 4e', '1/2a, 3a', '1/2b, 3b, 7' and '1/2c, 3c'; all harboured inlA, inlC and inlJ virulence genes. Listeria spp. were most frequently resistant to penicillin G (14/21 isolates, 66.7%) and tetracyclines (11/21 isolates, 52.4%).
本研究旨在确定从伊朗奶牛临床乳腺炎中分离出的李斯特菌属的流行率、特征和抗药性。从伊朗奶牛场的 207 份乳腺炎牛奶样本中检测到 21 份李斯特菌属，包括单核细胞增生李斯特菌（n=17）、无害李斯特菌（n=3）和伊氏李斯特菌（n=1）。单核细胞增生李斯特菌分离株分为血清群'4b、4d、4e'、'1/2a、3a'、'1/2b、3b、7'和'1/2c、3c'；均携带 inlA、inlC 和 inlJ 毒力基因。李斯特菌属对青霉素 G（14/21 株，66.7%）和四环素（11/21 株，52.4%）的耐药性最高。
