Detection of Escherichia coli harbouring extended-spectrum -lactamases of the CTX-M classes in faecal samples of common buzzards (Buteo buteo (original) (raw)

AI-generated Abstract

Detection of Escherichia coli harbouring extended-spectrum β-lactamases (ESBLs), particularly of the CTX-M classes, is rising in humans, and this study investigates their presence in free-living common buzzards (Buteo buteo) in Portugal. Out of 33 faecal samples examined from buzzards, 10 exhibited ESBL-producing E. coli, with specific identified genes including bla CTX-M-32 and bla CTX-M-1. This demonstrates a notable prevalence of CTX-M genes in wildlife, underlining the potential role of wild birds as reservoirs for antibiotic resistance genes.
