Abstract: Antimicrobial resistance in Gram-negative bacteria isolated from cloacal samples of chicks of Canarian Egyptian vultures was investigated. Prevalence of Salmonella was also studied. Forty-seven isolates, obtained from 23 animals, were analysed. Escherichia coli (n = 29), Proteus mirabilis (n = 17) and Salmonella spp. (n = 1) were identified using API 20E system. Antimicrobial susceptibility to 13 antibiotics included in nine different categories was determined using disk-diffusion technique. The higher percentages of susceptible E. coli isolates were found for aminoglycosides and cefoxitin, and the lower ones were found for ampicillin, enrofloxacin and tetracycline. Proteus mirabilis isolates were susceptible to most of antimicrobials tested. Multidrug resistance patterns were found in 13 E. coli and four Proteus mirabilis. Salmonella spp. was detected in one chick (4.37%), and the isolate was also resistant to ampicillin and tetracycline. Thirteen E. coli isolates and four Proteus isolates showed a multidrug-resistance pattern, being resistant at least to one antibiotic in three or more different antimicrobial categories. This high level of antibiotic resistance in chickens of an endangered bird may be a limitation for possible treatments of infections in this species, as well as representing a source of resistant bacteria for animal care staff and for other animals in wildlife recovery centres. A “One Health” approach to this problem is necessary to reduce the levels of antimicrobial resistance in wild birds.
