Multidrug-resistant phenotypes of escherichia coli isolates in wild canarian egyptian vultures (Neophron percnopterus majorensis). Animals 2021, 11:1692  https://doi.org/10.3390/ani11061692

The presence of multidrug-resistant (MDR) Escherichia coli in cloacal samples from Canarian Egyptian vultures was investigated. Samples were obtained from chicks (n = 65) and from adults and immature birds (n = 38). Antimicrobial susceptibility to 16 antibiotics included in 12 different categories was determined for 103 E. coli isolates. MDR was defined as acquired non-susceptibility to at least one agent in three or more antimicrobial categories. Forty-seven different resistance phenotypes were detected: 31 MDR (41 isolates) and 16 non-MDR (62 isolates). One isolate was resistant to all 12 antimicrobial categories and 2 phenotypes included resistance to 9 antimicrobial categories. Imipenem resistance was included in five MDR phenotypes, corresponding to five different isolates. Statistically significant differences in prevalence of MDR-phenotypes were found between chicks in nests and the rest of the animals, probably due to the shorter exposure time of chicks to antimicrobials. The main risk derived from MDR bacteria in scavengers is that it threatens the treatment of wild animals in rescue centres and could be transferred to other animals in the facilities. In addition to this, it could pose a health risk to veterinarians or other staff involved in wildlife protection programmes.
