ABSTRACT.- Ishii J.B., Freitas J.C. & Arias M.V.B. 2011.

The bacterial resistance profile was studied in several disorders affecting dogs and cats treated at the Small Animals Surgical Clinics Division of Veterinary Hospital of Universidade Estadual de Londrina. The disorders etiologic agents recovered were identified and Staphylococcus spp. was the most prevalent (27.6%), followed by Pseudomonas spp. (22.7%) and Escherichia coli (16.6%). In the antimicrobial susceptibility test using agar diffusion method, there was a high percentage of resistance to main antibiotics used to treat urinary tract infections, especially of Gram negative bacteria, which showed over 66% resistance to the antibiotics tested, except for norfloxacin. In wounds, only gentamicin and amikacin had resistance rates less than 50.0%. In otological disorders, less resistance to norfloxacin and higher to neomycin, and lower rates of resistance in Gram positive bacteria were observed. In the orthopedic cases, the Gram positive bacteria showed higher resistance to ciprofloxacin, and in peritonitis was found 100% resistance to various antibiotics. This study emphasizes the importance of bacterial identification and implementation of testing of susceptibility to antibiotics to choose the appropriate antimicrobial agent in the treatment of the major diseases seen in this field of small animal veterinary medicine. |
