Antimicrobial Susceptibility of Pseudomonas spp. Isolated from Dogs and Cats, and the Outcome of their Treatment of Infections

Abstract

Seventy-three strains of Pseudomonas aeruginosa, 8 strains of P. putida, and 29 strains of other Pseudomonas spp. were isolated from dogs and cats that had visited our hospital, Miyamoto Animal Hospital from year 2006 to 2013. All strains of Pseudomonas spp. were susceptible to amikacin and carbapenems. More specifically, 14 %, 14%, 7%, and 8% of P. aeruginosa were resistant to ofloxacin (OFLX), levofloxacin (LVFX), ciprofloxacin, and gentamicin, respectively ; 25% of P. putida and 3% of other Pseudomonas spp. were resistant to OFLX and LVFX, respectively. Pseudomonas spp. showed susceptibility to such antimicrobial drugs as fluoroquinolones, aminoglycosides, and fosfomycin, and these drugs were administered for the treatment of Pseudomonas infections. Ninety-five % of infections caused by P. aeruginosa, 75% of infections by P. pitida, and all cases infected by other Pseudomonas spp. were cured after administration of suitable antimicrobial drugs.
