Occurrence of cefotaxime-resistant and beta-lactamase-producing Enterobacterales in poultry from small-scale farms in the Copperbelt province of Zambia.

ABSTRACT:

Background

The inappropriate use of antimicrobials in poultry farming is associated with the emergence of antimicrobial-resistant Enterobacterales. This cross-sectional study aimed to identify various cefotaxime-resistant and β-lactamase-producing Enterobacterales and characterize their antimicrobial resistance profiles.

Methods

Pooled cloacal and meat samples collected from market-ready broiler chickens in Kitwe and Ndola districts of Zambia were screened for cefotaxime-resistant Enterobacterales. The samples were inoculated on MacConkey agar supplemented with 1 mg/L cefotaxime. The cefotaxime-resistant isolates were further subjected to antimicrobial susceptibility tests. Further, the isolated cefotaxime-resistant Enterobacterales were analysed for bla _CTX-M
