Vector-borne infectious diseases

Infections with the Berok strain of Plasmodium cynomolgi were induced in Macaca mulatta, Macaca fascicularis, Macaca nemestrina, Aotus lemurinus griseimembra, Aotus azarae boliviensis, and Saimiri boliviensis monkeys. Transmission was obtained with sporozoites developing in Anopheles peditaeniatus, Anopheles maculatus, Anopheles quadrimaculatus, Anopheles culicifacies, and Anopheles dirus mosquitoes. This strain of P. cynomolgi offers significant potential for a number of experimental studies. The parasite induces high-density parasite counts in both Old World and New World monkeys; rhesus monkeys readily support the development of gametocytes infectious to different anopheline mosquitoes routinely maintained in the laboratory; the gametocytes are infective to laboratory-maintained Anopheles albimanus, a vector rarely susceptible to plasmodia of Old World monkeys; encapsulated oocysts are produced in An. culicifacies as well as in Anopheles gambiae; and the parasite has been adapted to long-term in vitro culture.
