Prevalence of intestinal parasites in street dogs ( Canis lupus familiaris) with highlights on zoonosis in Lalitpur, Nepal
Abstract Background The presence of intestinal parasites influences the growth and well‐being of canids. Additionally, infected dogs and their faeces with considerably higher eggs/oocysts released per gram (epg/opg) of zoonotic parasites contribute to parasitic spillover to humans, domestic animals...

| Summary: | Abstract Background The presence of intestinal parasites influences the growth and well‐being of canids. Additionally, infected dogs and their faeces with considerably higher eggs/oocysts released per gram (epg/opg) of zoonotic parasites contribute to parasitic spillover to humans, domestic animals and sympatric wildlife. Objectives The current study aimed to reveal the prevalence of intestinal parasites (protozoa and helminths) and to list the zoonotically significant parasites in free‐roaming street dogs in Lalitpur Metropolitan City, Nepal. Methods Fresh faecal samples ( n = 332) were collected from feral dogs of varying ages and sexes and transported to the research laboratory. The copro microscopic examination was carried out via direct wet mount, formalin ethyl acetate sedimentation, saturated salt flotation, acid‐fast staining and sporulation techniques. Results Coproscopy revealed an overall 95.7% (318/332) prevalence rate with 23 diverse species of intestinal parasites (10 protozoa and 13 helminths). Among them, 5 protozoa and 11 helminths possessed zoonotic potential, and their overall prevalence was 92.5%. Helminth's overall prevalence was double that of the protozoa (87.7% vs. 43%). Polyparasitism was dominant over mono parasitism (79.5% vs. 16.3%), and co‐infection of up to seven species of parasites at a time was recorded. Conclusions Urban street dogs harboured a higher prevalence of intestinal parasites that varied with age and sex. Since most of the reported parasites are zoonotic, dog density and parasitic richness indicate a greater spillover risk to humans and domestic animals. Furthermore, this study also provides appropriate ‘baseline’ data for assessing effective control measures against parasitic infestations among street dogs and controlling their transmission to humans. |
