Red blood cell infected with malaria

Of all the infectious diseases: malaria (from the Italian mal laria, meaning 'bad air' ) has affected the most number of peple. But the true cause of this disease - which is credited with bringing down the Roman Empire - was not pinpointed until the nineteenth century. The first step was Alphonse Laveran discovery in 1880 of the malaris parasite - the Plasmodium, a single-celled animal or 'protozoan'. in 1894 Patrick Manson suggested that the infection might be transmitted by mosquitoes. And in 1897 Ronald Ross a British medical officer working in India, finally located in the stomach wall os an Anopheles mosquito the eggs that are intermediate state of the plasmodium life cycle.

Unsympathetic employers hampered Ross's work in India. Transferred to a region where human malaria was scarce, he undertook ground-breaking research on the malarial parasite of bird. In Italy, Battista Grassi stole Ross's thunder by working out the full sequence of transmission in human malaria. An ugly priority dispute followed, and, amid some controversy, ross received the 1902 Nobel Prize in Physiology or Medicine. But his work did provide the intellectual framework of establishing tropical medicine as a distinct speciality, prompting the search for the parasite-vector pairing often responsible for disease rife in hot climates.

Ross was one of the many who developed measure to control malaris through the eradication of mosquitoes. The introduction of the insecticide DDT during the Second World War was a great boon, and in 1955 the World Health Organization judged the conquest of malaria an attainable goal. But the campaign was thwarted. Mosquitoes quickly became resistant to DDT and the insecticide proved to be harmful to the environment.
