Antimicrobial resistance and molecular epidemiology of Klebsiella pneumoniae isolated from bovine mastitis in seven provinces in China.

ABSTRACT: The bovine mastitis caused by Klebsiella pneumoniae (K. pneumoniae) infection, lead to high death rate and severe economic loss. Currently, the regional epidemiological characteristics of K. pneumoniae in China are still unclear, especially the surveillance data on prevalence of extended-spectrum β-lactamase (ESBL)-producing K. pneumoniae in the cow are still limited. In this study, the epidemiology of K. pneumoniae from mastitis-infected cows in large-scale dairy farms in China were investigated. A total of 108 isolates of K. pneumoniae were isolated from 763 mastitis-associated milk samples collected from dairy farms in Jiangsu, Anhui, Hebei, Fujian, Guangdong, Shanxi and Zhejiang provinces in China. The whole genomes of 108 strains of K. pneumoniae were sequenced to identify their phylo
