On the Migration Route of the Infective Larvae ofNippostrongylus brasiliensis

Abstract

Some experiments were carried out on the migration route of the parasiteN. brasiliensis. The infective larvae migrate to the lungs via the lymphatic system and not by the blood stream. The larvae reached the lymphatic gland draining the site of infection from 12 to 17 hours after normal exposure to infection and the lungs from 18 hours onwards.
