Abstract:

Bacterial urinary tract infection is one of the most common infectious diseases of dogs. Uropathogenic bacteria commonly originate from the normal skin and gastrointestinal flora, causing ascending infections.

The purpose of our study was to identify the prevalence and the resistance rates among the bacteria isolated from dogs’ urinary tract systems. The samples were collected by cystocentesis from dogs that were referred to the Clinic of Internal Medicine at University of Veterinary Medicine Budapest, Hungary from September 01, 2015 to September 01, 2017.

In total we analized 61 positive urine cultures collected from 53 dogs. Beside microbiological data, the dogs’ age, sex, breed, symptoms, comorbidity, previous antimicrobial therapy and furher laboratory parameters were evaluated.

From the 61 samples 56 infections were monomicrobial and 5 of them resulted in two bacterial strains. The isolated bacterial species in order of their prevalence were Escherichia coli (57,4%), Proteus mirabilis (18,03%), Staphylococcus pseudointermedius (9,8 %), Enterococcus faecalis (8,2 %), Pseudomonas aeruginosa (3,3 %), Enterobacter spp. (3,3 %), β-hemolytic Streptococcus (3,3 %), Corynebacterium urealyticum (1,6 %), Mycoplasma canis (1,6 %) and Citrobacter koseri (1,6 %). Generally the isolated bacteria showed the highest in vitro resistance level to amoxicillin (22,7 %), sumetrolim (19,7 %), fluoroquinolones (18,2 %), amoxicillin-clavulanic acid (16,7 %) and gentamicin (15,2 %).

Our study is the first summary in Hungary regarding the prevalence and resistence data of canine uropathogenic bacteria.
