Bacteriological examination of urine samples from dogs with symptoms of urinary tract infection

Abstract

In the present study, a total of 100 urine samples obtained by antepubic cystocentesis from dogs with symptoms of urinary tract infection were examined bacteriologically. Bacteria were isolated from 38 of 100 urine samples. No significant difference was determined when the frequency of bacteriuria was compared between female and male dogs and in 2 different age groups (<2 and greater than or equal to2 years). The organisms were isolated in pure culture from 29 (76.31%) samples and were isolated in mixed culture from 9 (23.68%) samples. A total of 51 strains were isolated from the urine samples. Of the strains isolated, 12 (23.52%) were identified as Escherichia coli, 8 (15.68%) as Streptococcus spp., 6 (11.76%) as Micrococcus spp., 5 (9.80%) as Staphylococcus spp., 5 (9.80%) as Corynebacterium spp., 4 (7.84%) as Klebsiella pneumoniae, 3 (5.88%) as Proteus vulgaris, 2 (3.92%) as Pseudomonas aeruginosa, 2 (3.92%) as Citrobacter freundii, 2 (3.92%) as Acinetobacter calcoaceticus and 2 (3.92%) as Enterobacter agglomerans. Of the 51 strains examined, 46 (90.19%) were sensitive to amoxycillin/clavulonic acid, 40 (78.43%) to gentamicin, 39 (76.47%) to ampicillin/sulbactam, 31 (60.78%) to enrofloxacin, 30 (58.82%) to nitrofurantoin, 29 (56.86%) to kanamycin, 28 (54.90%) to oxytetracycline, 26 (50.98%) to cephalothin and danofloxacin, and 23 (45.09%) to sulphamethoxazole/trimethoprim.
