The zoonotic potential of dogs in Aboriginal communities in Central Australia

Abstract

This article reviews the established zoonoses from dogs, and identifies the potential burden of speculative zoonoses of canine origin in Aboriginal communities in Central Australia. A variety of organisms such as bacteria, viruses, and parasites including protozoa, ectoparasites and helminths (worms) have possible zoonotic capability; these organisms are discussed. Observational research was conducted in seven Aboriginal Town Camps of Alice Springs to describe the human and dog interactions and behaviours, and risk factors for transmission. Information was also gathered on the cultural significance of dogs to Aboriginal people in the community under observation. The relationship between Aboriginal people and their dogs appears to be not only one of companionship, but involves other more complex cultural factors. The contribution dogs make to infections and infestations of Aboriginal people in communities throughout Australia remains unclear. Education and dog health programs have an important role in reducing the risk of canine-related human morbidity in Aboriginal communities.
