Original publication title: Risk factors for the carriage of Campylobacter upsaliensis by dogs in a community in Cheshire.

Species:
dog

Plain-English summary

A study found that about 25% of healthy pet dogs in Cheshire tested positive for a bacteria called Campylobacter upsaliensis, which can sometimes cause gastrointestinal issues. Factors that increased the chances of a dog carrying this bacteria included living with another infected dog, being small and under three years old, having a household with fish, and being fed commercial dog treats or human food scraps. While the presence of this bacteria doesn’t always lead to illness, it’s good to be aware of these risk factors. If your dog shows any signs of digestive upset, consult your veterinarian for advice.

Abstract

Samples of faeces were taken from 183 healthy pet dogs in a census-based, cross-sectional study in Cheshire; culture methods were used to detect any Campylobacter species and a direct PCR was used to detect Campylobacter upsaliensis. Forty-six of the dogs were positive for C upsaliensis by either culture or direct PCR, giving a prevalence of 25.1 per cent (95 per cent confidence interval [CI] 19.0 to 32.1 per cent). One sample was positive by culture for Campylobacter jejuni (95 per cent CI 0.0 to 3.0 per cent) and one for Campylobacter lari. Multivariable logistic regression identified risk factors for the carriage of C upsaliensis by a dog as: living with another dog that also carried C upsaliensis; being small rather than medium-sized; being less than three years old; living in a household that kept fish; being fed commercial dog treats; and being fed human food titbits, particularly in the dog's bowl.
