We investigated the prevalence of 30 known virulence factor genes (VFGs) in uropathogenic E. coli (UPEC) from two geographically distinct feline populations, using a PCR-based approach. E. coli isolates were also subjected to macrorestriction analysis to assess their phylogenetic relationships. VFG profiles differed considerably according to the geographic(More)
We investigated the feasibility of bacteriophage therapy to combat canine and feline Escherichia coli urinary tract infections (UTIs) by testing the in vitro lytic ability of 40 naturally occurring bacteriophages on 53 uropathogenic E. coli (UPEC). The mean number of UPEC strains lysed by an individual bacteriophage was 21/53 (40%, range 17-72%). In total,(More)
Prostatic diseases commonly warrant surgical intervention. Early castration may prevent the development of benign prostatic hyperplasia, prostatitis, and cavitary lesions (prostatic abscesses or cysts). In intact dogs that present with these disorders, castration should always be part of the specific surgical treatment because it enhances treatment success(More)
OBJECTIVE To compare survival of dogs with a congenital portosystemic shunt (CPSS) that received medical or surgical treatment. DESIGN Prospective cohort study. ANIMALS 126 client-owned dogs with a single CPSS. PROCEDURES Dogs were examined at 1 of 3 referral clinics, and a single CPSS was diagnosed in each. Dogs received medical or surgical treatment(More)
Older cats with chronic renal failure (CRF) commonly develop urinary tract infections (UTI). Uropathogenic Escherichia coli (UPEC) is identified as the causal agent of UTI in most affected cats. Infections are often complicated, and UPEC infections may persist or recur in these cats. Antibiotic sensitivity profiles have been used to distinguish relapsing or(More)
