Gastrointestinal parasites of indigenous pigs (Sus domesticus) in south‐central Nepal
Abstract Background Intestinal parasites have a significant impact on productivity of pigs. Additionally, presence of zoonotic parasites in pig faeces used as fertilizer and ingestion of raw or undercooked pork products originated from parasite‐infested pigs pose a risk to human health.

Additionally, presence of zoonotic parasites in pig faeces used as fertilizer and ingestion of raw or undercooked pork products originated from parasite‐infested pigs pose a risk to human health. Objectives The aim of the study was to estimate the prevalence and diversity of gastrointestinal (GI) parasites in indigenous pigs (Sus domesticus) maintained under traditional rearing system in Nepal. Methods Fresh faecal samples (n = 100) were collected from the pigs of varying age and sex maintained in 18 small‐scale farms in south‐central Nepal. Samples were processed using various standard methods and examined for parasite eggs, cysts or oocysts. Results Prevalence of GI parasites in indigenous pigs was 91%, comprising of 14 different genera of protozoans and helminths. Male pigs generally had a higher (97.5%) prevalence of GI parasites than females (87%). While 90% of the suckling and weaner piglets were positive for the GI parasites, all growers and 85% the adult pigs were infected with the parasites. Entamoeba spp. were the primary protozoans in all age groups. Strongyloides sp. was more prevalent helminths in suckling and weaner piglets, whereas Ascarid spp. were higher in both growers and adults. Triplet infection was higher (33.3%) in suckling and weaner piglets, while quadruplet and pentuplet infections were higher (p < .05) among growers (46.7%) and adults (30%), respectively. Conclusions The indigenous pigs harbour a higher prevalence and greater diversity of GI parasites. GI parasitism varies by sex and age of the pigs.https://doi.org/10.1002/vms3.536BalantidiumChwanchegastrointestinal parasitesNepalswinezoonosis |
