Factors related to<i>Campylobacter</i>spp. carriage in client-owned dogs visiting veterinary clinics in a region of Ontario, Canada

Abstract

SUMMARYFrom July 2008 until May 2009, 240 client-owned pet dogs from seven veterinary clinics in the Region of Waterloo, Ontario, Canada participated in a study to determine pet-related management factors that may be associated with the presence ofCampylobacterspp. in dogs. The prevalence ofCampylobacterspp. carriage in our study population of pet dogs was 22%, with 19% of the dogs positive forC. upsaliensis, and 3% positive forC. jejuni. A significant risk factor from multivariable logistic regression models for bothCampylobacterspp. andC. upsaliensiscarriage was having homemade cooked food as the dog's diet or added to its diet, and a significant sparing factor for both models was treatment with antibiotics in the previous month. Increasing age of the dog decreased the odds ofCampylobacterspp. andC. upsaliensiscarriage. Based on the high prevalence ofCampylobacter, and specificallyC. upsaliensis, further research concerning pet dogs as a risk factor for campylobacteriosis in humans is warranted.</jats:p
