What was discovered
Ross found the parasite in the stomach of an Anopheles mosquito fed on the blood of a patient and demonstrated the full cycle in birds; Grassi proved it in humans. It founded medical entomology.
Ross (Nobel 1902) and Grassi had a bitter dispute; Grassi demonstrated the cycle in humans with Anopheles.
