Explanation:
Sir Ronald Ross was born in Almora, India in 1857 to Sir C.C.G. Ross, a General in the Indian Army, and his wife Matilda. At the age of eight, he was sent to England to be educated and spent much of his childhood with an aunt and uncle on the Isle of Wight. During his early years he developed interests in poetry, literature, music, and mathematics, all of which he continued to engage in for the rest of his life.
Although he had no predisposition to medicine, at the age of 17 he submitted to his father’s wish to see him enter the Indian Medical Service. He began his medical studies at St. Bartholomew’s Hospital Medical College, London in 1874 and sat the examinations for the Royal College of Surgeons of England in 1879. He took the post of ship surgeon on a transatlantic steamship while studying for, and gaining the Licentiate of the Society of Apothecaries, which allowed him to enter the Indian Medical Service in 1881, where he held temporary appointments in Madras, Burma, and the Andaman Islands. During a year’s leave, from June 1888 to May 1889, he developed his scientific interests and studied for the Diploma in Public Health from the Royal Colleges of Physicians and Surgeons in England and took a course in bacteriology under Professor E. E. Klein. He also married Miss Rosa Bloxam, who accompanied him to Bangalore when he returned for duty as a staff surgeon.
On 20 August 1897, in Secunderabad, Ross made his landmark discovery. While dissecting the stomach tissue of an anopheline mosquito fed four days previously on a malarious patient, he found the malaria parasite and went on to prove the role of Anopheles mosquitoes in the transmission of malaria parasites in humans.
He continued his research into malaria in India, using a more convenient experimental model, malaria in birds. By July 1898, he had demonstrated that mosquitoes could serve as intermediate hosts for bird malaria. After feeding mosquitoes on infected birds, he found that the malaria parasites could develop in the mosquitoes and migrate to the insects’ salivary glands, allowing the mosquitoes to infect other birds during subsequent blood meals.
