Aerobic bacterial isolates and susceptibility to antimicrobial agents in canine osteomyelitis

Abstract

The aim of this work was to detect aerobic bacteria in osteomyelitis process in dogs with bone exposure. The API-Bio Merieux Identification System was used to identify the bacteria. Susceptibility in vitro was verified by the agar diffusion method, to 14 different antibiotics. The most frequent bone involved was tibia (35%). Gram positive cocci represented 68.3% from isolates and the Gram negative bacteria 31.7%. Staphylococcus spp, Streptococcus spp and Enterococcus spp were the most frequent genus, representing, respectively, 34.1%, 14.6%, and 14.6% of the total bacteria strains (41 strains). Enterobacteria were isolated in 26.8%. Cocci Gram positive presented good susceptibility to amoxicillin associated with clavulanic acid. Grain negative microorganisms, the enterobacteria and Pseudomonas sp, showed high resistance profile.
