Das Gupta and his supervisor Robert Knowles first described Plasmodium knowlesi as a distinct species, and as a potential cause of human malaria in 1932 when they described the morphology of the parasite in macaque blood, and demonstrated that it could infect three human patients (in each case it was used to induce fever with the hope of treating another infection).Also in 1932, John Sinton and H. W. Mulligan further described the morphology of the parasite in blood cells, determined it to be a distinct species, and named it Plasmodium knowlesi in honor of Robert Knowles.
