Are assistant animals a source of zoonotic disease?

Assistant animals (Animal-assisted interventions (AAIs) have had positive effects on the health of owners and people. But, could they transmit disease?

 A study evaluated the presence of potentially zoonotic diseases in animals involved in assistant animals. A total of 190 animals were investigated between 2015 and 2017, including equids, dogs, cats, birds, rabbits, rodents, and one goat were studied. Almost 1/3 of the animals worked in health facilities, 24.2% in schools, and 44.7% in petting zoos.

Data obtained from physical examinations, fecal analysis, fur, and skin examination were examined. More than one third of the animals were infected with parasites. Twenty one percent of the dogs had zoonotic parasites such as Ancylostomatidae, Eucoleus aerophilus, Toxocara canis, and Giardia duodenalis and a cat had G. duodenalis. In horses and dogs, two mycosis agents Nannizzia gypsea and Paraphyton mirabile were found. 

This study showed how assistant animals might be a source of infections to humans either through direct contact or via environmental contamination. It has been recommended to do animal screenings and active surveillance to reduce the risk of exposure.
