E. coli was isolated from 90 (86.5%) samples but no ETEC was detected, likely because ETEC fimbriae confer the species specificity of the pathogen. Resistance to at least one antimicrobial agent was detected in 89.9% of E. coli isolates, being AMR levels extremely high (>70%) for tetracycline and streptomycin, and very high (>50%) for ampicillin and sulfamethoxazole-trimethoprim. Resistance to other critically important antimicrobials such as colistin and extended-spectrum cephalosporins was 2.2%, and 1.1%, respectively, and was encoded by the mcr-1 and blaSHV-12 genes. Multidrug resistance was displayed by 80% of the resistant E. coli and blaSHV-12 gene shared plasmid with other AMR genes. In general, resistance patterns in E. coli from vultures mirrored those found in pigs. C. difficile was detected in three samples (2.9%), two of them belonged to PCR-ribotype 078 and one to PCR-ribotype 126, both commonly found in pigs. All C. difficile isolates were characterized by a moderate to high level of resistance to fluoroquinolones and macrolides but susceptible to metronidazole or vancomycin, similar to what is usually found in C. difficile isolates from pigs. Thus, vultures may contribute somewhat to the environmental dissemination of some pig pathogens through their acquisition from pig carcasses and, more importantly, of AMR for antibiotics of critical importance for humans. However, the role of vultures would likely be much lesser than that of disposing pig carcasses at the SFS. The monitoring of AMR, and particularly of colistin resistant and ESLB-producing E. coli, should be considered in pig farms used as sources of carcasses for SFS.application/pdfesopen accessAnimales vectores.Animals as carriers of disease.Resistencia a los medicamentos.Pathogenic bacteria.Buitres leonados - Alimentación.Griffon vulture - Feeding and feeds.Bacterias patógenas.Drug resistance.Artículohttps://doi.org/10.1111/tbed.13470https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es
