<s>[INST] context: Haemoflagellates: Flagellates found in blood and tissues. Medically impoant Haemoflagellates require two hosts to complete their life cycle and are therefore called digenetic or heteroxenous. They live in the blood and tissues of human and other veebrate hosts, and in the gut of insect vectors. Haemoflagellates infecting human belong to two genera, in the family, Trypanosomatidae-- Trypanosoma and Leishmania. Members of this family have a nucleus, a kinetoplast and a single flagellum. The kinetoplast consists of a deeply staining parabasal body and a adjacent dot-like blepharoplast. The blepharoplast and parabasal body are connected by one or more delicate fibrils. The flagellum arises from the blepharoplast. The poion of the flagellum which is inside the body of the parasite is called the axoneme or axial filament Multiplication in veebrate and in veebrate hosts is by binary fission. No sexual cycle is known. Basic morphology of haemoflagellates.
