Charles Louis Alphonse Laveran

Charles Louis Alphonse Laveran was a French physician who identified protozoan parasites as the cause of malaria and received the 1907 Nobel Prize in Physiology or Medicine.

Ronald Ross: A British physician who demonstrated that mosquitoes transmit malaria parasites between hosts. His mosquito experiments extended the account of malaria transmission after Laveran identified its parasite.
Malaria: A mosquito-borne infectious disease caused by Plasmodium parasites. Laveran’s work established that this disease has a parasitic cause.
Constantine, Algeria: A city in northeastern Algeria and an important center of French colonial administration. Laveran made his malaria discovery while serving as a military physician there.
Mosquito-malaria transmission: The transfer of malaria parasites to humans through bites from infected female Anopheles mosquitoes. Identifying the parasite made it possible to investigate how it moves between hosts.
Laveran’s malaria discovery: Laveran’s 1880 observation of malaria parasites in the blood of an infected patient. This was the direct observation that established the parasitic cause of malaria.
Patrick Manson: A Scottish physician whose research established that mosquitoes transmit several human diseases. His work on mosquito transmission helped shape the research context for malaria.
Plasmodium: A genus of single-celled parasites that infect vertebrates and are transmitted by mosquitoes. Laveran identified malaria parasites in the blood of infected patients.
French Army Medical Corps: The medical service responsible for the health of personnel in the French armed forces. Laveran’s military posting exposed him to malaria cases and enabled his investigations.
Anopheles: A genus of mosquitoes that includes the species transmitting human malaria parasites. Later research connected Laveran’s parasite to a specific mosquito vector.
Quinine: An alkaloid derived from cinchona bark and used to prevent and treat malaria. Quinine treated malaria before its parasite was understood, distinguishing therapy from explanation.
