Effects of the host immune response on the longevity, fecundity and position in the intestine of XXXX in @entity19 .

@entity2199 @entity8416 @entity308 @entity19 @entity281
In female NIH strain @entity19 , expulsion of a primary @entity281 of the @entity2199 @entity8416 began on day 8 and was virtually complete by day 14 of @entity281 . In secondary and tertiary @entity281 , 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 @entity281 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 @entity281 fecundity was @entity308 . The @entity308 of fecundity occurred slightly in advance of worm loss. During the stable phase of @entity281 , @entity8416 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 @entity8416 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 @entity8416 and expulsion is not merely due to a change in the position of the worms.
