Isolated pathogens and antibiogram in clinical cases of urinary tract infection in dogs

Abstract

Aim: The objective of this study is to identify the causes of urinary tract infections (UTIs) in dogs and to establish an antibiogram of the isolated organisms. Materials and Methods: Urine samples were collected via catheterization from 51 dogs suspected of having UTIs and admitted to VCC, LUVAS, Hisar. Bacteria were identified in 46 of these samples based on cultural characteristics and confirmed using the Vitek2 compact system. All isolates were subjected to vitro antimicrobial sensitivity testing.Results: The urine samples positive for bacteria showed pure colony growth in 84.78% of cases and mixed growth in 15.21%. Among the 46 positive isolates, 19 (37.25%) were identified as E. coli, 9 (17.64%) as Staphylococcus spp., 4 (7.84%) as Pseudomonas spp., 3 (5.88%) as Klebsiella spp., 2 (3.92%) as Proteus spp., 1 (1.96%) as Acinetobacter lwoffii, and 1 (1.96%) as Cronobacter dublinensis. The isolates exhibited the highest sensitivity to Imipenem (65.32%) and Meropenem (65.04%), while showing complete resistance to Oxytetracycline (100%) and Tetracycline (100%). Conclusion: Among dogs affected by UTIs, E. coli and Staphylococcus spp. were the most frequently isolated gram-negative and gram-positive bacteria, respectively. Antimicrobial sensitivity testing showed a notable portion of these bacteria to be resistant to multiple drugs.
