Antibiotic susceptibility of Pseudomonas aeruginosa strains isolated from dogs with external otitis

Abstract

The purpose of this study was to determine susceptibility to antibiotics in strains of P. aeruginosa isolated from dogs with external otitis in Callao, Perú. Twenty strains were tested for their susceptibility to 11 antibiotics by the disk diffusion method. The aminoglycosides presented the best sensitivity (94.4%). Multiresistance was registered in 70%. Mongrel breed were the most affected (50%). The aminoglycosides and then the fluoroquinolones remain as treatment options.
