Traité des fièvres palustres (1884)

Summary

Alphonse Laveran's "Traité des fièvres palustres" (1884) presents the concrete, demonstrated central thesis that malaria is caused by a microscopic parasite residing within red blood cells. This work details Laveran's groundbreaking discovery of Plasmodium, the protozoan responsible for malarial fevers, observed during his post-mortem examinations of soldiers. He meticulously describes the parasite's morphology, its presence within the blood of infected individuals, and its correlation with the cyclical fever patterns characteristic of the disease.

The book's key ideas include the parasitic etiology of malaria, distinguishing it from earlier miasmatic or germ theories. Laveran establishes the need for microscopic examination to identify the causative agent and links specific parasitic forms to different types of malarial fevers. Readers gain a foundational understanding of protozoology in relation to infectious disease and the observational, empirical method that led to a paradigm shift in understanding malaria.

Key concepts

• Plasmodium — The protozoan parasite identified by Laveran as the causative agent of malaria.
• Hematozoa — Microscopic organisms found within the blood, a term Laveran used for the malaria parasite.
• Paroxysm — A sudden, recurrent attack of disease symptoms, specifically the cyclical fevers of malaria.
• Red Blood Cells — The host cells within which the Plasmodium parasite develops and multiplies.
