The ''Trichuris'' worms are so called due to their characteristic whipe like structure. They have a broad posterior end tapering to a long and narrow neck which is inserted into the caecal mucosa. They have a direct lufe cycle, moving directly into the definitive host from the infective L1 egg stage. Once ingested the larva is freed from the egg casing and forms a mucosal nodule in which to develop before emreging into the lumen of the gastointestinal system.
