Enterococci as opportunistic bacteria are important for human health. Due to the prevalence and ease of acquisition and transfer of their genes, they are an excellent indicator of environmental contamination and the spread of antimicrobial resistance. The aim of the study was to assess the prevalence ofEnterococcusspp. in wild birds in Poland, determination of antimicrobial susceptibility and WGS analysis ofEnterococcus(E.)faeciumandE. faecalis. For this purpose, 138 samples from various species of free-living birds were tested, with 66.7% positive results. Fourteen species were detected, withE. faecalisbeing the most common, followed byE. casseliflavusandE. hirae. In antimicrobial susceptibility testing, 10.0% ofE. faecalisand 50.0% ofE. faeciumshowed resistance to one antimicrobial agent, in addition the MDR phenotype which was found in oneE. faecium. The most common resistance phenotype included tetracycline and quinupristin/dalfopristin. The WGS analysis confirmed the significant advantage of the virulence gene diversity ofE. faecalisstrains overE. faecium. In addition, plasmid replicons were found in 42.0% ofE. faecalisand 80.0% ofE. faecium. The obtained results confirm free-living birds can be a reservoir ofEnterococcusspp. with a considerable zoonotic potential.
