Infecção urinária em cães doentes renais : etiologia e resistência

Abstract

Infections of the genitourinary system are among the most frequent in the clinical routine of small animals, being essential the institution of a correct antimicrobial therapy according to the uropathogen susceptibility test, avoiding the spread of bacterial resistance to the antibiotics. A clinical study was performed with 34 canine animals, of both sexes and different ages, attended at the University Veterinary Hospital, submitted to uroculture, with the objective of evaluating urinary tract infection in renal diseased dogs, identifying the associated bacterial pathogens and verifying their antibiotic susceptibility in vitro. The uroculture was positive in 12 dogs, mostly males, with no racial predisposition and with a mean age of 8.7 years. Most of de UTI were monobacterial, with the most common microorganisms being Pseudomonas sp e Staphylococcus sp. Imipenem was the antibiotic with the best overall sensitivity profile and the one with the highest resistance was Ampicilin. The variance of the epidemiological profile and susceptibility to uropathogen in the present study reinforces the importance of the veterinarian in the prevention and control of the disease, in addition to the need for further research in search of new antimicrobial agents.
