ABSTRACT

Aim: This study aims to determine the etiology of urinary tract infection (UTI) in dogs and to develop an antibiogram of organisms isolated.

Materials and Methods: Urine samples were collected either through catheterization or cystocentesis from 35 dogs suspected of UTI admitted to VCC, LUVAS, Hisar. Bacteria were identified on the basis of cultural characteristics in 22 samples, and all the isolates were subjected to in vitro antimicrobial sensitivity testing.

Results: The urine samples found positive for bacteria yielded pure colony growth in 77.27% and mixed growth in 22.73% samples, respectively. Escherichia coli (29.62%) and Streptococcus spp. (29.62%) were the most prevalent microorganisms followed by Staphylococcus spp. (22.22%), Klebsiella spp. (11.11%), Pseudomonas spp. (3.7%), and Bacillus spp. (3.7%). Overall, maximum sensitivity of isolates was found toward ceftriaxone/tazobactam (88.88%) and least toward amoxicillin and cloxacillin (29.62%).

Conclusion: E. coli and Streptococcus spp. were the most predominant bacteria isolated from UTI affected dogs. In vitro sensitivity revealed a significant proportion of bacteria to be multidrug resistant.
