“…in a group of healthy dogs using PCR. 22 However, studies of healthy dogs in the United Kingdom and Ireland, also using PCR, have shown a high prevalence of infection (upwards of 40% in some cases) with both C. jejuni and C. upsaliensis , 29,30 similar to what was found in this study. The potential Campylobacter spp.-related zoonotic risk associated with canine feces is also supported by the intensity of infection in many of the samples.…”

“…9,16,20 Previous reports have implicated domestic dogs as a potential source of these zoonoses. 2,6,9,11,15,21 In this study, the prevalence of T. canis in fecal samples was greater than that previously identified in owned dogs in the United States and Canada, 17,22,23 although it was within the range reported for stray dogs 24,25 and dogs in northern Canadian aboriginal communities. 1,26 This variation in prevalence of infection could be the result of differences in anthelmintic treatment among the different groups of dogs.…”

Five genera of potentially zoonotic bacteria and parasites were detected in environmentally collected fecal samples from a remote indigenous community in Northern Saskatchewan, Canada. Organisms identified include Toxocara canis, Echniococcus granulosus, Giardia duodenalis, Cryptosporidium spp., and Campylobacter spp. The prevalence and intensity of Giardia spp. and Campylobacter spp. in fecal samples was particularly remarkable. Three-quarters of samples tested contained at least one zoonotic species of Campylobacter, and C. jejuni-containing feces had an average of 2.9 × 105 organisms/g. Over one-half of samples tested contained Giardia spp. with an average of 9,266 cysts/g. Zoonotic G. duodenalis Assemblage A was the only Giardia spp. genotype identified. These data suggest that canine feces have the potential to pose a significant health risk to Canadians in rural and remote indigenous communities.

“…However, it is not yet clear whether the contamination comes from patients or the hospital environment (Weese and Fulford 2011). Lefebvre et al (2006b) reported the first human epidemic strain PCR-ribotype 027 in a healthy 4-year-old toy poodle that visited patients in healthcare settings in Ontario on a weekly basis. In 2009, reported the acquisition of toxigenic C. difficile by a therapy dog on its paws during a visit to an acute care facility.…”

Zoonoses are infections or diseases that can be transmitted between animals and humans through direct contact, close proximity or the environment. Clostridium difficile is ubiquitous in the environment, and the bacterium is able to colonise the intestinal tract of both animals and humans. Since domestic and food animals frequently test positive for toxigenic C. difficile, even without showing any signs of disease, it seems plausible that C. difficile could be zoonotic. Therefore, animals could play an essential role as carriers of the bacterium. In addition, the presence of the spores in different meats, fish, fruits and vegetables suggests a risk of foodborne transmission. This review summarises the current available data on C. difficile in animals and foods, from when the bacterium was first described up to the present.

Companion Animal Zoonoses

Companion animals can harbor a wide range of parasites, some of which are transmissible to humans. The overall burden of human diseases attributable to companion animal -associated parasites is unknown and varies greatly between regions. The risks associated with some are often overstated while others are largely ignored, and the range of illness can extend from mild and selflimited to fatal.
