RESUMO
Wild birds have been considered to be reservoirs of enteric human pathogens and vectors of resistance dissemination to the environment. During annual migration, they potentially play a role in the epidemiology of human associated zoonoses. The aim of this study was to investigate the frequency of isolation and antimicrobial susceptibility profiles of Enterobacteriaceae members isolated from cloacal swabs of common European wild birds. Fifty-five cloacal swabs were taken during birds' entrance evaluation in a rescue centre for injured wild birds in the Province of Messina (Sicily, Italy). All samples were examined for the presence of members of the family Enterobacteriaceae using standard methods and on the isolated strains antibiotic susceptibility testing was performed. Eighty three Enterobacteriaceae strains were isolated from raptors, waterbirds and passerines. The bacterial species isolated were: Escherichia coli, Proteus mirabilis, Proteus vulgaris, Citrobacter freundii, Enterobacter cloacae, Klebsiella oxytoca, Salmonella Typhimurium, Escherichia vulneris, Enterobacter amnigenus biogroup 2, Salmonella Duesseldorf and Hafnia alvei. The isolates showed significant frequencies of antibiotic resistance. Multiresistance to three or more groups of antibiotics also occurred. None of them have shown a phenotypic Extended Spectrum Beta Lactamase (ESBL) profile.
