In vitro Maturation of the Exoerythrocytic Stage of Plasmodium knowlesi Observed under Phase Contrast Microscopy

Journal of Parasitology (1990)

Pascal Millet William E. Collins Claude E. Monken Bobby G. Brown

Exoerythrocytic stages of Plasmodium knowlesi were obtained in primary culture of rhesus monkey hepatocytes. The development of a single parasite was followed with phase contrast microscopy until release of merozoites in slightly less than 5 days. This direct observation may offer opportunities to determine visually factors that may influence specific steps of schizont development.

Changes in Hematologic Values During Infection of New World Monkeys With Plasmodium falciparum and P. vivax.

PubMed (1998)

G. Gale Galland Carla L. Morris Sullivan Jacquelin M. Roberts William E. Collins

Owl (Aotus sp.) and squirrel (Saimiri sp.) monkeys are used frequently in malaria vaccine trials, during which the animals are monitored daily for parasitemia and general well-being. Every 2 weeks, blood samples are taken, and hematology and chemistries are performed. We examined 97 cases of malarial infection in owl and squirrel monkeys, whose parasitemia increased by. 22,000 parasites/uL daily during a 14-day interval. After malaria challenge, unprotected animals had significant changes in hematologic values. These changes could not be completely attributed to the increase in the parasite counts.

Adaptation of a chloroquine-resistant strain of Plasmodium vivax from Indonesia to New World monkeys.

American Journal of Tropical Medicine and Hygiene (2000)

William E. Collins John S. Sullivan D J Fryauff Jeremy Kendall Veronica M. Jennings

The spread of chloroquine-resistant Plasmodium vivax from Papua New Guinea and Indonesia poses a serious health threat to areas of Southeast Asia where this species of malaria parasite is endemic. A strain of P. vivax from Indonesia was adapted to develop in splenectomized Aotus lemurinus griseimembra, Aotus vociferans, Aotus nancymai, and Saimiri boliviensis monkeys. Transmission to splenectomized Saimiri monkeys was obtained via sporozoites. Chemotherapeutic studies indicated that the strain was resistant to chloroquine and amodiaquine while sensitive to mefloquine. Infections of chloroquine-resistant P.vivax in New World monkeys should be useful for the development of alternative treatments.

William E. Collins Michael E. Wayda

Abstract : An index to Federal Aviation Administration (FAA) Office of Aviation Medicine Reports (1964-1995) and Civil Aeromedical Institute Reports is presented for those engaged in aviation medicine and related activities. The index lists all FAA aviation medicine reports published from 1961 through 1995: chronologically (pp. 1-41), alphabetically by author (pp. 43-50), and alphabetically by subject (pp. 51-72).

ADAPTATION OF A STRAIN OF PLASMODIUM VIVAX FROM INDIA TO NEW WORLD MONKEYS, CHIMPANZEES, AND ANOPHELINE MOSQUITOES

Journal of Parasitology (2001)

JoAnn S. Sullivan Elizabeth Strobert Chunfu Yang Carla L. Morris G. Gale Galland

A strain of Plasmodium vivax from India was adapted to develop in splenectomized Saimiri boliviensis, Aotus lemurinus griseimembra, A vociferans, A. nancymai, A. azarae boliviensis, hybrid Aotus monkeys, and splenectomized chimpanzees. Infections were induced via the inoculation of sporozoites dissected from the salivary glands of Anopheles stephensi and An. dirus mosquitoes to 12 Aotus and 8 Saimiri monkeys; transmission via the bites of infected An. stephensi was made to 1 Aotus monkey and 1 chimpanzee. The intravenous passage of infected erythrocytes was made to 9 Aotus monkeys and 4 chimpanzees. Gametocytes in 13 Aotus monkeys and 4 chimpanzees were infectious to mosquitoes. Infection rates were markedly higher in mosquitoes fed on chimpanzees. PCR studies on 10 monkeys injected with sporozoites revealed the presence of parasites before their detection by microscopic examination. The India VII strain of P. vivax develops in Aotus and Saimiri monkeys and chimpanzees following the injection of parasitized erythrocytes, or sporozoites, or both. The transmission rate via sporozoites to New World monkeys of approximately 50% may be too low for the testing of sporozoite vaccines or drugs directed against the exoerythrocytic stages. However, the strain is highly infectious to commonly available laboratory-maintained anopheline mosquitoes. Mosquito infection is especially high when feedings are made with gametocytes from splenectomized chimpanzees.

ADAPTATION OF A STRAIN OF PLASMODIUM FALCIPARUM FROM GHANA TO AOTUS LEMURINUS GRISEIMEMBRA, A. NANCYMAI, AND A. VOCIFERANS MONKEYS

American Journal of Tropical Medicine and Hygiene (2003)

JoAnn S. Sullivan James J. Sullivan Allison E. Williams Katharine K. Grady Amy Bounngaseng

A strain of Plasmodium falciparum from Ghana was adapted to Aotus lemurinus griseimembra, A. nancymai, and A. vociferans monkeys. Gametocytes in splenectomized A. nancymai were infective to Anopheles freeborni mosquitoes. Sporozoite transmission was accomplished in two splenectomized A. nancymai with prepatent periods of 22 and 25 days. The Ghana III/CDC strain of P. falciparum is susceptible to treatment with chloroquine and mefloquine.
