The objectives of this study were to determine the prevalence, characterization and antibiotic resistance of Pasteurella multocida isolated from calves with respiratory infection in Iran. P. multocida was detected in 141/169 bovine respiratory infection cases on Iranian dairy and beef farms. P. multocida were grouped into serogroups A (126/141), D (12/141), and B (3/141). Of the P. multocida isolates, all harboured the psl, ompH, oma87, fimA, ptfA, nanB, and nanH genes, 139/141 had hsf-2, and 115/141 pfhA, and tadD. The isolates were most frequently resistant to penicillin G (43/141 resistant isolates; 30.5%) and streptomycin (31/141; 22%).
本研究的目的是确定从伊朗患有呼吸道感染的犊牛中分离出的多杀性巴氏杆菌的流行情况、特征及抗生素耐药性。在伊朗奶牛场和肉牛场的169例牛呼吸道感染病例中，有141例检测到多杀性巴氏杆菌。多杀性巴氏杆菌分为血清群A（141例中的126例）、D（141例中的12例）和B（141例中的3例）。在多杀性巴氏杆菌分离株中，所有菌株都携带psl、ompH、oma87、fimA、ptfA、nanB和nanH基因，141例中有139例携带hsf-2，141例中有115例携带pfhA和tadD。分离株最常对青霉素G耐药（43/141例耐药分离株；30.5%）和链霉素耐药（31/141例；22%）。
