Sand-fly Phlebotomus Papatasi (phlebotominae): a General Review with Special Reference to Zoonotic Cutaneous Leishmaniasis in Egypt.

Leishmania are digenetic protozoa which inhabit two hosts, the sandfly where they grow as promastigotes in the gut, and the mammalian macrophage where they grow as amastigotes. Sandfly (or sand fly) is a colloquial name for any species or genus of flying, biting, blood-sucking Dipteran encountered in sandy areas. In the United States, sandfly may refer to certain horse flies that are also known as "greenheads" (family Tabanidae), or to members of the family Ceratopogonidae, also known in Florida and elsewhere as a sand gnat, sandflea, no-see-um (no-see-em, noseeum), granny nipper, chitra, punkie, or punky. Outside the United States, sandfly may refer to members of the subfamily Phlebotominae within the Psychodidae. Biting midges (Ceratopogonidae) are sometimes called sand flies or no-see-ums (no-see-em, noseeum). New Zealand sandflies are in the Austrosimulium genus, a type of black fly. Of 500 known phlebotomine species, only some 30 of them have been positively identified as vectors of the disease. Cutaneous leishmaniasis (ZCL) is a protozoan disease well documented not only in Egypt, but in nearly all the East Mediterranean Countries. It is prevalent in the Egyptian Sinai Peninsula with at least three identified foci.
