Characterization of the dog urine microbiota and its susceptibility to antimicrobials

Abstract

The urinary tract of dogs is usually considered to be a sterile environment, with the exception of the distal urethra, which is composed of resident microorganisms from the vagina or foreskin. Approximately 14% of dogs can develop urinary tract infection (UTI) during their lifetime, being more common in females and the elderly. The indiscriminate use of antimicrobials in the treatment and prevention of diseases of the urinary tract can contribute to the development of bacterial resistance. The aim of this study was to identify the microbiota involved in disorders of the urinary tract of dogs in the municipality of Formiga, Minas Gerais and to establish the susceptibility profile of these agents against antimicrobials commonly used in the veterinary clinical routine. The samples used were granted by a veterinary clinical analysis laboratory in the municipality of Formiga - MG, with 13 biological samples being made available and submitted to culture and antibiogram. In eight (61.5%) of the 13 samples, it was possible to notice the presence of Staphylococcus spp., followed by E. coli (15.4%), Enterococcus sp. (7.7%), Streptococcus sp. (7.7%) and Proteus sp. (7.7%). Regarding the susceptibility profile to antimicrobials, it was possible to conclude that for amoxicillin + clavulanic acid, with approximately 61.5% of the samples, it was the antimicrobial with the best efficiency.
