Biraj Mohan Das Gupta
Biraj Mohan Das Gupta or Dasgupta (, c. 1889 – 1945) was a Bengali parasitologist, known for his discovery, with Robert Knowles, of the '' Plasmodium'' species now known as '' Plasmodium knowlesi''. Biography After qualifying as a physician, Das Gupta was appointed in 1921 to a position as a researcher and assistant surgeon at the Calcutta School of Tropical Medicine. At the Calcutta School of Tropical Medicine, in 1931 H. G. M. Campbell detected the ''Plasmodium'' species now known as ''P. knowlesi'' in a macaque imported from Singapore. Campbell showed his discovery to his supervisor Lionel Everard Napier, who injected the strain into three monkeys, one of which developed symptoms of malaria. Aware of the Protozoological Department's search for a monkey malaria strain, Napier and Campbell gave the infected monkey to Das Gupta, working under Knowles. Das Gupta maintained the ''Plasmodium'' species by serial passage in monkeys until Knowles returned from leave. In 1932, Kno ...

Bengal Presidency
The Bengal Presidency, officially the Presidency of Fort William and later Bengal Province, was a subdivision of the British Empire in India. At the height of its territorial jurisdiction, it covered large parts of what is now South Asia and Southeast Asia. Bengal proper covered the ethno-linguistic region of Bengal (present-day Bangladesh and the Indian state of West Bengal). Calcutta, the city which grew around Fort William, was the capital of the Bengal Presidency. For many years, the Governor of Bengal was concurrently the Viceroy of India and Calcutta was the de facto capital of India until 1911. The Bengal Presidency emerged from trading posts established in Mughal Bengal during the reign of Emperor Jahangir in 1612. The East India Company (HEIC), a British monopoly with a Royal Charter, competed with other European companies to gain influence in Bengal. After the decisive overthrow of the Nawab of Bengal in 1757 and the Battle of Buxar in 1764, the HEIC expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British India
The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance on the Indian subcontinent. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods: *Between 1612 and 1757 the East India Company set up Factory (trading post), factories (trading posts) in several locations, mostly in coastal India, with the consent of the Mughal emperors, Maratha Empire or local rulers. Its rivals were the merchant trading companies of Portugal, Denmark, the Netherlands, and France. By the mid-18th century, three ''presidency towns'': Madras, Bombay and Calcutta, had grown in size. *During the period of Company rule in India (1757–1858), the company gradually acquired sovereignty over large parts of India, now called "presidencies". However, it also increasingly came under British government over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parasitologist
Parasitology is the study of parasites, their hosts, and the relationship between them. As a biological discipline, the scope of parasitology is not determined by the organism or environment in question but by their way of life. This means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology, immunology, genetics, evolution and ecology. Fields The study of these diverse organisms means that the subject is often broken up into simpler, more focused units, which use common techniques, even if they are not studying the same organisms or diseases. Much research in parasitology falls somewhere between two or more of these definitions. In general, the study of prokaryotes falls under the field of bacteriology rather than parasitology. Medical The parasitologist F.E.G. Cox noted that "Humans are hosts to nearly 300 species of parasitic worms and over 70 species of protozoa, some derive ...

Plasmodium
''Plasmodium'' is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of ''Plasmodium'' species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect (mosquitoes in majority cases), continuing the life cycle. ''Plasmodium'' is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, ''Plasmodium'' is in the order Haemosporida and family Plasmodiidae. Over 200 species of ''Plasmodium'' have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range. Evolutionary relationships among different ''Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasmodium Knowlesi
''Plasmodium knowlesi'' is a parasite that causes malaria in humans and other primates. It is found throughout Southeast Asia, and is the most common cause of human malaria in Malaysia. Like other ''Plasmodium'' species, ''P. knowlesi'' has a life cycle that requires infection of both a mosquito and a warm-blooded host. While the natural warm-blooded hosts of ''P. knowlesi'' are likely various Old World monkeys, humans can be infected by ''P. knowlesi'' if they are fed upon by infected mosquitoes. ''P. knowlesi'' is a eukaryote in the phylum Apicomplexa, genus ''Plasmodium'', and subgenus ''Plasmodium''. It is most closely related to the human parasite ''Plasmodium vivax'' as well as other ''Plasmodium'' species that infect non-human primates. Humans infected with ''P. knowlesi'' can develop uncomplicated or severe malaria similar to that caused by ''Plasmodium falciparum''. Diagnosis of ''P. knowlesi'' infection is challenging as ''P. knowlesi'' very closely resembles other spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
