Prevalence and Antibiotic Sensitivity of Motile Aeromonas in Dogs

Abstract

The present study was carried out to assess the prevalence of motile Aeromonas sp. in the faeces of healthy dogs and to evaluate its susceptibility to some anti-microbial agents. Rectal swabs from 55 domestic dogs were examined for Aeromonas species using alkaline peptone water (pH 8.4) as the enrichment medium and Aeromonas Selective Agar containing 5 mg/l ampicillin as the plating medium. Identification and antibiotic resistance of motile Aeromonas strains was performed using Gram Negative Breakpoint ID panel. After examining these samples, aeromonads were isolated from three (5.45%) dogs. Of those, one was A. sobria, and two were A. caviae. While all isolated strains were sensitive to amikacin, cefoperazone, cefotaxime, cefotetan, ceftazidime, ceftriaxone, cefuroxime, ciprofloxacin, gentamicin, imipenem, piperacillin, tetracycline, ticarcillin, ticarcillin/clavulanate, tobramycin, and trimethoprim/sulfamethoxazole, they were resistant to ampicillin, and ampicillin/sulbactam. In addition, a strain of A. caviae was also resistant to aztreonam. As a result, in the present study, information about the prevalence of Aeromonas in dogs, susceptibility to antibiotics of these microorganisms and its importance for both animal and public health were discussed.
