1 jan 1880 ano - Malaria Parasite Discovered

Descrição:

Alphonse Laveran, a military doctor in France's Service de Santé des Armées discovered the malaria parasite in the military hosptial in Constantine.

"A single-celled parasite known as a sporozoan causes malaria."

"After transferring to a new post on Algeria's North African coast, Laveran investigated his theory. On October 20, 1880, while looking through a crude microscope at the blood of a febrile soldier, he saw crescent-shaped bodies that were nearly transparent except for one small dot of pigment. In preceding decades the brownish-black pigment hemozoin (now known to be the product of hemoglobin digestion by the malaria parasite) had been found in cadaveric spleens and blood of malaria victims by several investigators including Meckel, Virchow, and Frerichs. Laveran subsequently examined blood specimens from 192 malaria patients and saw pigment-containing crescents in 148 sufferers (Laveran, 1978). He ultimately recognized four distinct forms in human blood that would prove to be the malaria parasite in different stages of its life cycle: the female and male gametocyte, schizont and trophozoite stages."
