Medical Definition of Trichuris trichiura

1. The whipworm of humans, a species that causes trichuriasis; the body is filiform and slender in the anterior three-fifths, and more robust posteriorly; females are 4 or 5 cm long, males are shorter (with coiled caudal extremity and a single eversible spicule); eggs are barrel-shaped, 50 to 56 by 20 to 22 um, with double shell and translucent knobs at each of the two poles; humans are the only susceptible hosts and usually acquire infection by direct finger-to-mouth contact or by ingestion of soil, water, or food that contains larvated eggs (development in the soil takes 3 to 6 weeks under proper conditions of warmth and moisture, hence distribution is chiefly tropical); larvae escape from eggs in the ileum, mature in approximately a month, and then pass directly into the caecum without undergoing a parenteral migration as occurs with Ascaris lumbricoides; adults may persist for 2 to 7 years.
