The Intensity of Infection and Public Health Perception of Potentially Zoonotic Intestinal Parasites of Dogs in Kwara Central, Nigeria

Background: The close relationship between dogs and humans and the possibility of intestinal parasite transmission from dogs to humans calls for frequent assessment of these potential zoonotic intestinal parasites in dogs and the possibility of their transmission to humans. Objectives: This study aimed to determine the presence, intensity of infection, and public health perception of potentially zoonotic intestinal parasites in dogs of Kwara Central, Nigeria. Methods: The study was conducted in ۲۸ locations in Kwara Central Senatorial District of Kwara State, Nigeria. Three hundred and five healthy dogs were sampled. Two hundred and thirty respondents (dog owners or handlers) were questioned using a well-structured questionnaire containing open-ended and closed-ended questions. Fecal samples from the sampled dogs were subjected to the direct fecal smear technique, simple fecal centrifugation flotation technique, formalin-ethyl acetate concentration technique, and the modified Ziehl-Neelsen staining technique. Oocysts or eggs per gram of feces were counted using the modified McMaster technique. Results: Seven different intestinal parasites (Ancylostoma spp., Cryptosporidium spp., Dipylidium caninum, Isospora spp., Strongyloides stercoralis, Toxocara spp., and Uncinaria stenocephala) were detected, with a prevalence ranging from ۲.۳۰% to ۲۵.۲۵%. Of these parasites, ۶ were zoonotic. The mean intensities of infection were ۹۱.۴۳ eggs per gram (EPG) for D. caninum¸ ۹۶.۵۲ EPG for S. stercoralis, ۱۲۹.۳۶ ±۲۸.۱۲ oocysts per gram (OPG) for Isospora spp., ۱۶۵.۱۷±۱۹.۸۸ for Toxocara spp., ۲۴۰.۰۰±۴۴.۴۲ for EPG for U. stenocephala, and ۳۰۳.۶۴±۳۱.۸۳ EPG for Ancylostoma spp. Some dog owners and handlers were not cautious about possible zoonotic parasite transmission from dogs. Conclusion: Zoonotic intestinal parasites of dogs are present and prevalent in Kwara Central, Nigeria. There is a need to educate the public on the possibility of zoonotic parasite transmission to humans.
