Abstract

Background: Dogs and dzos are important domestic animals in human communities in high altitude landscapes, and are the potential carriers of different parasites. There is a potential risk of zoonotic parasite transmission between dzos and free-ranging dogs. Therefore, evaluating and managing the parasites could play a role in safeguarding health and overall well-being.
Objectives: The study aimed to investigate the prevalence and diversity of intestinal parasites in free-ranging dogs, owned dogs, and dzos in Upper Humla, Nepal.
Methods: Fecal samples (N=151), including 109 from free-ranging dogs, 12 from owned dogs and 30 from dzos, were collected. Applying direct wet mount and acid-fast staining methods, microscopic examination of fecal samples was carried out.
Results: The overall prevalence of GI parasites was 75.49%, out of which 75.23% were in free-ranging dogs, 66.67% in owned dogs, and 80% in dzos. Nineteen parasite species (18 confirmed) were recorded with nine species in dzos, seven in owned dogs, and seventeen in free-ranging dogs. The triplet infection was higher in free-ranging dogs, duplicate infection was higher in owned dogs, and pentuplet infection was higher in dzos. The dogs and dzos of Upper Humla were commonly infected with Entamoeba spp., ascarids, Cryptosporidium spp., Eimeria spp., and Taenia spp.
Conclusion: Intestinal parasites can substantially threaten human populations through zoonotic transmission. Controlling and managing the parasitic infection in dogs and dzos can reduce damage to human health.
