Abstract

Ultrastructural studies were carried out on biochemically confirmed Leishmania aethiopica in the oesophagus of naturally-infected, wild-caught sandflies, Phlebotomus pedifer. The parasites with an infection rate of 2.8% were either free in thelumen or attached to the cuticular lining by hemidesmosomes. Previously undescribed pseudopodia-like projections which seemed to enhance the anchorage of L. aethiopica in the oesophagus were observed.

Résumé

Des études ultrastructurales ont été menées sur Leishmania aethiopica reconnue biochemiquement dans l'oesophage des mouches, Phlebotomus pedifer sauvages capturées et infectées naturellement. Les parasites ayant un taux d'infection de 2.8% étaient libres dans le lumen ou étaient attachés au cuticule á travers les hemidesmosomes.

Précedemment des projections des pseudopodes non encore décrites qui semblaient exagérer l'ancrage de L. aethiopica dans l'oesophage étaient observées.
