Molecular characterization of extended-spectrum β-lactamase-producing isolated from postpartum uterine infection in dairy cattle in India.

Background And Aim: Selection and dissemination of plasmid-encoded extended-spectrum β-lactamase (ESBL) among confers resistance to beta-lactam antibiotics. The purpose of this study was to determine the prevalence and molecular characteristics of ESBL-producing organisms isolated from dairy cattle with a uterine infection.

Materials And Methods: Bacterial isolates (n=62) were characterized by biochemical test for genus and species determination.
