SYNOPSIS.Leucocytozoon neavei and Leucocytozoon caulleryi were found in guinea fowl in Tanzania and Leucocytozoon schoutedeni in chickens. The minimum time required for sporogony of L. neavei at approximately 20 C was ∼7 days in Simulium adersi and Simulium nyasalandicum. Gametocytes of L. neavei , which appeared mature, were seen in the peripheral blood of guinea fowl chicks 14 days after experimenal inoculation with sporozoites from S. adersi or S. nyasalandicum. Sporogony of L. schoutedeni was followed in “Simulium impukane,” S. adersi, Simulium vorax and S. nyasalandicum. Oocysts were ∼12 μm in diameter. Sporogony of some individuals was completed in 6–7 days at 20 C. Each oocyst produced ∼50–60 sporozoites. Gametocytes were detected in the peripheral blood of a chicken 10–14 days after experimental inoculation with sporozoites of L. schoutedeni from S. adersi and “S. impukane.”
