Abstract

Inocula of encysted larvae, excysted larvae or infected meat all resulted in aggregated distributions of adults in the anterior small intestine. However, implantation studies indicated that the larvae could establish anywhere between the duodenum and the colon. The site of larval establishment determines the subsequent location of adult T. spiralis; the site of establishment was due largely to influences such as intestinal motility, size of inoculum and the size of the vehicle of infection. Predominantly female inocula were dispersed similarly to heterosexual inocula while male populations were dispersed more widely.
