Crithidia fasciculata
''Crithidia fasciculata'' is a species of parasitic protist. ''C. fasciculata'', like other species of ''Crithidia'' have a single host life cycle with insect host, in the case of ''C. fasciculata'' this is the mosquito. ''C. fasciculata'' have low host species specificity and can infect many species of mosquito.
==Life cycle==
''C. fasciculata'' is found in two morphologically different life cycle stages - the free swimming choanomastigote form, which has a long external flagellum for motility, and the attached, immotile, amastigote form in the mosquito gut. Amastigotes excreted in the faeces contaminates the mosquito habitat, contamination of flowers during nectar feeding is common.
Transmission of ''C fasciculata'' primarily occurs when amastigotes, washed into standing water, are ingested by mosquito larvae. The amastigotes are typically found in the rectum of a larva. Each molt of the larva results in loss of infection, but it is generally quickly re-acquired from the environment by ingestion of more amastigotes. When the fourth instar larva pupates the amastigote infection is maintained in the gut through metamorphosis giving rise to an infected adult mosquito.
