INFECTION AND TRANSMISSION STUDIES WITH PLASMODIUM-SIMIOVALE IN THE MACACA-MULATTA MONKEY

Six different anophelines.sbd.Anopheles freeborni, A. balabacensis balabacensis, A. maculatus, A. stephensi, A. atroparvus and A. quadrimaculatus.sbd.were susceptible to infection with P. simiovale when fed upon splenectomized M. mulatta monkeys between the 1st and 26th days of patent parasitemia. Transmission was obtained via the bites of A. balabacensis balabacensis and A. maculatus mosquitoes. Prepatent periods in M. mulatta monkeys following sporozoite inoculation ranged from 11-20 days with a median of 14 days.
