Abstract

Highlights: Campylobacter was isolated from 17% of dogs and 14.7% of cats in Northern Italy. C. jejuni was the most common Campylobacter species in both dogs and cats. Origin was a risk factor for Campylobacter colonization in dogs. Dogs from shelters were at significantly higher risk than household dogs. Household and stray pets represent potential sources of exposure for humans. Abstract: Campylobacteriosis is among the most common bacterial causes of human gastroenteritis worldwide and pet ownership has been identified as a risk factor for Campylobacter infection in humans. Since canine and feline prevalence data are scarce in Italy, the present study was carried out to assess the prevalence, species distribution and risk factors for Campylobacter infection in dogs and cats under different husbandry conditions. Rectal swabs were collected from 171 dogs (household pets, n = 100; shelter-housed dogs, n = 50; dogs from breeding kennels, n = 21) and 102 cats (household pets, n = 52; shelter-housed cats, n = 21; free-roaming cats n = 29) in Northern Italy. Campylobacter was isolated from 17% ( n = 29) of dogs and 14.7% ( n = 15) of cats. C. jejuni was the most common isolate in both species ( Campylobacter spp.-positive dogs, 55.2%; Campylobacter spp.-positive cats, 53.3%), followed by C. upsaliensis ( Campylobacter spp.-positive dogs, 27.6%; Campylobacter spp.-positive cats, 40%). Other Campylobacter species were rarely detected, but included C. hyointestinalis subsp. hyointestinalis, C. lari and C. coli in dogs and C. coli and C. helveticus in cats. Among considered variables (sex, age, origin, diarrhoea, season of sampling), origin was identified as a risk factor for dogs, with shelter-housed dogs at higher risk than household dogs (odds ratio, 2.84; 95% CI 1.17, 6.92; P = 0.021). The results of this study, particularly the high prevalence of C. jejuni in Campylobacter -positive animals, demonstrated that household and stray dogs and cats in Northern Italy might pose a zoonotic risk for humans. Moreover, biosecurity measures should be improved in dog shelters.
