Summary

In female NIH strain mice, expulsion of a primary infection of the nematode Trichinella spiralis began on day 8 and was virtually complete by day 14 of infection. In secondary and tertiary infections, the number of larvae which established in the intestine was normal, but expulsion began on day 6 and was complete on day 10. In a primary infection the shedding of larvae by female worms began on day 5, reached its peak on days 6–7, began to decrease on day 8 and was minimal by day 10. In secondary and tertiary infections fecundity was depressed. The depression of fecundity occurred slightly in advance of worm loss. During the stable phase of infection, T. spiralis occurred in the anterior half of the small intestine. During expulsion, living worms were found increasingly in more posterior parts of the gut but their fecundity did not vary with position. After direct inoculation into the posterior ileum, adult and larval T. spiralis remained in the posterior half of the small intestine. In this position, larvae established in normal numbers, grew and reproduced normally. Therefore, any part of the small intestine was a suitable site for T. spiralis and expulsion is not merely due to a change in the position of the worms.
