[Cortico-adrenal reaction in rats to attempts of reinfestation by Strongyloides ratti (author's transl)].
After spontaneous recovery from infestation by Strongyloides ratti, reinfestation by a new generation of adult parasites is not possible if the primary infestation was by 5,000 or 10,000 larvae administered in one or more contacts and if the secondary infestation takes place 3 weeks after. Reinfestation becomes possible again 51 days after recovery from a primary infestation by 15,000 larvae. However although the larvae do not reach the adult stage, they do begin their migration and cause hypersecretion of gluco-cortico-steroids. There is thus a contrast between the ease with which the organism rapidly and lastingly prevents the transformation of larvae into adults and the difficulty in neutralising the larvae and preventing them from triggering a stress.
