The biologist Grassi mapped out the life cycle of Plasmodium in_______?
Show answer Hide answer
Answer: C. 1898
Explanation
Giovanni Battista Grassi successfully mapped the complete life cycle of the malaria parasite Plasmodium in eighteen ninety-eight. His Italian research team demonstrated that mosquitoes transmit malaria parasites between human hosts. This discovery provided the crucial missing link in understanding how vector-borne infectious diseases spread. Malaria is a severe human parasitic disease caused by protozoans of the genus Plasmodium. Grassi worked alongside other scientists like Ronald Ross to uncover the complex mosquito vector lifecycle. Entomological studies proved that female Anopheles mosquitoes serve as the definitive hosts for Plasmodium.
Mapping the parasite lifecycle enabled public health officials to design effective mosquito eradication campaigns. Vector control remains a primary strategy for preventing malaria transmission in tropical regions globally. Historical breakthroughs in parasitology saved millions of lives through targeted disease prevention measures. 1896 is earlier than the year Grassi finalized his comprehensive mosquito transmission parasite studies. 1897 marks related research milestones, but eighteen ninety-eight is the established date for mapping the cycle. 1899 is later than the completion of Grassi's landmark publication on Plasmodium mosquito lifecycles.
