Abstract: Campylobacteriosis is one of the leading causes of gastroenteritis in humans and various researches suggested that owning a pet is a risk factor for the disease. To determine the prevalence and risk indicators for Campylobacter sp. infecting dogs attending veterinary practice at TVCC, DUVASU, Mathura, 100 dogs with and without the clinical symptoms of diarrhoea were examined and the prevalence of Campylobacter sp. was 51.0%. Breed wise prevalence showed that nondescript (73.68%) dogs were more likely to carry Campylobacter sp. A significant difference in isolation rates was observed between younger and older dogs: 56.58% of the younger dogs (≤ 1 year) were positive, compared with 33.33% of adult dogs (> 1 year) (p<0.01) as seen at the veterinary University, Mathura, India. Dogs sharing a household with another dog, dogs that had not received antibiotic treatment in the previous months and the age of the dog were significant indicators of Campylobacter carriage. Recent diarrhoea or vomiting in dogs with Campylobacter, breed, sex or vaccination status were not statistically significant. The high prevalence of Campylobacter in puppies supports the hypothesis that dogs, particularly young ones shed Campylobacter spp., which can be of impact for public health.
