AMR prevalence in domestic dogs in Hungarian cities

Abstract

This study investigates the prevalence of ESBL-producing Enterobacterales in dog feces collected from urban green spaces in two major Hungarian cities, Budapest and Debrecen. Of the 399 samples analyzed, 26 isolates of ESBL-producing Enterobacterales were identified. Among these, 88.5% (23/26) demonstrated resistance to three or more antimicrobial classes. The genomic DNA of the bacterial isolates was analyzed using polymerase chain reaction and whole genome sequencing. Most ESBL-encoding genes were plasmid-mediated, suggesting acquired resistance rather than intrinsic. Sequence types, phylogenetic grouping and virulence factors were also determined, revealing a genetically diverse set of isolates.
