A Case Study in the Scientific
Dr. Ross Discovers Malaria Plasmodium
||Malaria Killed over
4000 people in 1941. In 2000 less than 5 people died from malaria.
This was made possible by the work performed by an English Physician and
Scientist Dr. Ronald Ross.
Dr. Ross knoew that the disease of malaria was caused by an organism
called plasmodium. The Plasmodium was found in the
blood stream of infected individuals but it was not known how it got
there. Dr. Ross also knew that people who slept in tents that were
not protected were more likely to contract malaria that those with
protected sleeping envrironments. Int ehe unprotected sleeping areas
he found large amounts of mosquitos. Dr. Ross hypothesized
that if the mosquito was spreading malaris, mosquitoes that had bitten
infected patients would pick up the plasmodium parasite.
In Dr. Ross's experiment, the control group was the patients not infected and sleeping in netted areas. The experimental group were the people that had malaria and were being bitten by the mosquitoes. The hypothesis was proven correct, and what stands now is the theory. A hypothesis proven correct by experimentation.
