Detection and characterisation of extended-spectrum and plasmid-mediated AmpC β-lactamase produced by isolates found at poultry farms in Bosnia and Herzegovina.

Extended-spectrum β-lactamases (ESBLs) hydrolyse extended-spectrum cephalosporins (ESC) and aztreonam. As ESBL-producing organisms have been identified in food producing animals, the aim of our study was to detect and analyse such isolates from poultry. Antibiotic susceptibility of the isolates was determined with disk-diffusion and broth microdilution methods.
