Isolation of bacterial pathogens and their antibiotic sensitivity in the cases of urinary tract infection in dogs

One of the most prevalent diseases in companion animals is urinary tract infection. Bacterial urinary tract disease is a common cause of morbidity in dogs and cats, and among the leading reason for antimicrobial use. Improper therapy can lead to variety of health concerns for the dog or cat (e.g., failure to resolve infection, development of antimicrobial resistance). Present study is conducted to isolate bacterial pathogens and to determine their antibiotic sensitivity from the dogs affected with urinary tract infection. A total of 28 urine samples from the dogs suspected of UTI were collected by catheterization and subjected to the cultural isolation and antimicrobial susceptibility testing. Out of 28 samples subjected to cultural isolation total 17(60.71%) samples were found positive for bacterial growth. Out of total 17 positive samples 4 (23.52%) samples were positive for E. coli, 3(17.64%) for Proteus spp., 3(17.64%) for Staphylococcus spp., 2(11.67%) for Klebsiella spp., 2(11.67%) for Pseudomonas spp., 2 (11.67%) samples were found to be positive for mix infection, with one case showing E. coli + Stephylococcus spp. and the other showing E. coli + Proteus spp. Whereas 1(5.88%) sample were found positive for Streptococcus spp. Ceftriaxone + Tazobactam was shown to have the highest overall sensitivity (88.23%), followed by Amoxicillin + Sulbactam (76.47%), gentamicin (76.47%), ciprofloxacin (70.58%), ampicillin (47.05%), and penicillin (11.76%).
