Background and Aim The extended-spectrum beta-lactamases (ESBLs), as well as
carbapenemases, are considered as the foremost resistance determinants throughout the …

This study was conducted to reveal the phylogenetic background, to detect the genes
encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to …

ABSTRACT A total of 295 ceftiofur-resistant Escherichia coli isolates were obtained from 489
cloacal samples collected at five different Belgian broiler farms with the aim to evaluate the …

Simple Summary Antimicrobial resistance is a phenomenon spreading through animals and
humans, often with food as a vector. In this study, the presence of extended-spectrum β …

Escherichia coli is quite a common and sometimes pathogenic bacterium that can cause
acute to severe infection in poultry birds affecting their performance. E. coli can also cause a …

Antimicrobial resistance in bacteria is the most urgent global threat to public health, with
extended-spectrum β-lactamase-producing Escherichia coli (ESBL-E. coli) being one of the …

The prevalence of multidrug resistant, extended spectrum β-lactamase (ESBL)-producing
Enterobacteriaceae is increasing worldwide. The present study aimed to provide an …

Extended spectrum-lactamase (ESBL) producing Escherichia coli infections are a major
clinical problem that has attained a global health concern. This study aimed to determine the …

A total of 405 Escherichia coli from the chicken production chains in Nigeria were
investigated for ESBL-production and 4 isolates were identified as ESBL producers. They …
