In the early 1900's, malaria was one of the leading causes of death in tropical areas. While scientists
knew that malaria was caused by Plasmodium bacteria, they did not know how the bacterium was being
transferred between individuals. An experiment investigated the role of mosquitoes in malaria
transmission. Mosquitoes were allowed to feed on one of two groups of people group one consisted of
individuals infected with malaria, group two consisted of uninfected individuals. After feeding the
mosquitoes were dissected and examined for presence of Plasmodium bacteria.
