Occurrence of Escherichia coli producing extended spectrum β-lactamases in food-producing animals

Abstract Multidrug resistance due to the production of extended-spectrum beta-lactamases (ESBLs) is a major problem in human as well veterinary medicine. These strains appear animal and microbiomes can be source infection both healthcare, accordance with One Health theorem. In this study we examined prevalence ESBL-producing bacteria food-producing animals. We collected 100 porcine 114 poultry samples examine ESBL producers. Isolates were identified using MALDI-TOF system their antibiotic susceptibility was tested disk diffusion method. gene families phylogroups detected by polymerase chain reactions. The producers relatively high sample groups: 72 (72.0%) 39 (34.2%) isolates Escherichia coli chosen for further investigations. most common CTX-M-1 (79.3%). Most belong commensal E. phylogroups. could divided into three phylogroups, while distribution more varied. summary, are prevalent faecal animals, dominance group enzymes
