          Abstract

          Se estudia la susceptibilidad de Lutzomyia townsendi a la infección con Leishmania spp. sobre lesiones experimentales de hamsteres. Se estudia la frecuencia y distribución de los amastigotos en la dermis, relacionándola con la profundidad que alcanza el estilete bucal del insecto. Una correlación positiva, con significante coeficiente de correlación, se establece entre la frecuencia de los parásitos a una profundidad de 100-150 nm en la dermis y el éxito de la infección de los flebótomos.

          Translated abstract

          The susceptibility of Lutzomyia townsendi to infection with amastigotes of Leishmania spp. from experimental lesions in hamsters is studied. A good correlation is found when the number of infected sandflies are compared with the distribution and density of parasites in the dermis, taking into account the size of the fascicle, particularly the length of labrun and dental depth in maxillae. Considerations are made on the susceptibilities of some anthropophilic sandflies from America that are considered as good vectors.
