Comparative occurrence and antibiogram of extended-spectrum β-lactamase-producing among post-weaned calves and lactating cows from smallholder dairy farms in a parallel animal husbandry area.

Background And Aim: Inappropriate overuse of antimicrobials might be associated with the spreading of antimicrobial-resistant bacteria in animal-based food products. Extended-spectrum β-lactamase (ESBL)-producing have been recognized as an emerging global problem in a One Health approach. This study aimed to assess the occurrence and antimicrobial-susceptible profiles of ESBL-producing among post-weaned calves and lactating cows in a parallel animal husbandry area.
