Trichuris vulpis Infection in an Indian Tribal Population

Abstract

Stools from 28 of the 82 inhabitants on remote Little Andaman Island in India were examined for parasite eggs and cysts. Trichuris trichiura eggs were found in 27, Trichuris vulpis eggs in 5, Strongyloides stercoralis larvae in 3, hookworm eggs in 15, Entamoeba histolytica and Entamoeba coli cysts each in 9, Giardia lamblia in 6, Retortamonas sp. in 3, Iodoamoeba sp. in 2, and Chilomastix sp. in 2 stools. Ascaris lumbricoides eggs were not seen. The occurrence of T. vulpis eggs in 5 stools and the absence of A. lumbricoides eggs were considered unusual findings.

Prevalence of gastrointestinal parasites of stray dogs impounded by the Society for the Prevention of Cruelty to Animals (SPCA), Durban and Coast, South Africa : short communication

“…Surprisingly, the parasite was absent in the previous studies in South Africa 16,17 but reported in stray dogs in neighbouring Zimbabwe 1 8 . Human infections by T. vulpis have been reported 9,12,25 and have been attributed to humans being in continuous contact with environments contaminated by infected dogs.…”

Paleoparasitological results for rodent coprolites from Santa Cruz Province, Argentina

“…Bundy & Cooper (1989) stated that gastrointestinal helminthosis is estimated to be the most common of all parasitic infections, with more than a quarter of the world's population infected with four human nematode species, Trichuris trichiura Linnaeus occupying the second order of importance, after Ascaris lumbricoides Linnaeus. The zoonotic potential of Trichuris was also documented for Trichuris vulpis, parasite of dog worldwide (Singh et al 1993, Dunn et al 2002. It is probable that Trichuris spp of Patagonic rodents in ADG could be infectious for humans, because during the Holocene, humans and animals shared caves and shelters.…”
