Phlebotomine Vectors of Human Disease.

Abstract

Collections of phelbotomines were made in Nov. 1982 at and near Morogoro, Tanzania following confirmed reports of cutaneous leishmanias in humans. One new species of Sergentomyia (Sintonius) was discovered; other species were reared in the laboratory. A Phlebotomus (Larroussius) sp., near orientalis a vector of visceral leishmaniasis and new to Egypt, was identified from a small lot of Egyptian sand flies. A sibling species of Lutzomyia ylephiletor was discovered after studying collections of sand flies from Guatemala. Material from Peru and Surinam including anthropophilic species. Were identified and studied. Two manuscript were completed one confirming demonstration of transovarial transmission of a Phlebovirus (Rio Grande Virus) by sand flies for the first time; the other summarizing the ecology of leishmaniasis in Panama with vector information. A new Leishmania that uniquely invades red blood cells in lizards in Tanzania is being studied in sand flies. Its pathogenicity to hamsters will be evaluated. Development of Leishmania mexicana (Texas strain) is being studied in lab-bred sand flies infected by amastigotes in hamsters. The antigenicity of promastigotes in various parts of the infected flies is being studied using monoclonal antibodies. Development in sand flies of a human strain of Leishmania n. sp. from the Dominican Republic is also being studied.
