Abstract

Adult Strongyloides ratti were expelled from the small intestine of rats starting 14—18 days after a primary infection. In a secondary infection very few adult worms developed and most of these were expelled before day 14. At the time of expulsion the worms migrated posteriorly in the intestine and their size decreased.
