2016 ACVIM Forum Research Abstract Program

Two hundred and eighty-two cultures were submitted on 195 patients during the study time period. Forty-seven cultures performed on 13 patients were excluded due to the presence of ureteral stents (5 patients), chemotherapy (2 patients), diabetes mellitus (2 patients), transitional cell carcinoma (2 patients), urinary incontinence and cystic calculi (1 patient each). A total of 235 cultures submitted on 182 patients were included in the final analysis. There were 8 intact males, 52 castrated males, 5 intact females, and 117 spayed females. There were 40 positive urine cultures (17.0% of all cultures) obtained on 33 patients (18.1% of all dogs). Of all positive cultures, the most frequently determined diagnosis was SBU (18 cultures, 45%), followed by pyelonephritis (16 cultures, 40%), then UTI (6 cultures, 15%). There were no statistically significant observed relationships between any IRIS stage and diagnosis (P = 0.635). The number of positive cultures, regardless of patient diagnosis, was not statistically significant between IRIS stages (P = 0.432). Escherichia coli was the most frequently observed isolate (29/40 cultures, 72.5%).
