Anopheles Aitkenii
''Anopheles aitkenii'' is a species of mosquito belonging to the genus ''Anopheles''. The species group (Reid and Knight, 1961) is composed of forest forms with small unornamented brown adults, where the females usually indistinguishable. Female feed on vertebrate blood and known to cause simian malaria and filariasis Filariasis is a parasitic disease caused by an infection with roundworms of the Filarioidea type. These are spread by blood-feeding insects such as black flies and mosquitoes. They belong to the group of diseases called helminthiases. These par ....

Sydney Price James
Lieutenant Colonel Sydney Price James (17 September 1870 – 17 April 1946) was a British physician, parasitologist, and malariologist who served in the Indian Medical Service. Life and work James was born at Highgate to the Hereford family of Thomas Edward and Margaret, daughter of Rev. George Price. As a child he read books on travel and adventure and took a keen interest in outdoors natural history. An older brother went to South Africa with the navy and died from malaria in 1900, another was a keen photographer who invented Velox paper, and still another became a farmer in Rhodesia. He went to study medicine at Guy's Hospital but a scholarship at St Mary's Hospital made him move and he graduated in 1895. He joined the Indian Medical Service in 1896 and trained at Netley before reaching Bombay. He was posted in Waziristan in 1897 to deal with a plague outbreak and later joined the Tochi Valley Expedition during which he was invalided by typhoid back to England. During this b ...

Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anopheles
''Anopheles'' () is a genus of mosquito first described and named by J. W. Meigen in 1818. About 460 species are recognised; while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus ''Plasmodium'', which cause malaria in humans in endemic areas. '' Anopheles gambiae'' is one of the best known, because of its predominant role in the transmission of the most dangerous malaria parasite species (to humans) – '' Plasmodium falciparum''. The name comes from the Ancient Greek word 'useless', derived from , 'not', 'un-' and 'profit'. Mosquitoes in other genera (''Aedes'', ''Culex'', '' Culiseta'', '' Haemagogus'', and ''Ochlerotatus'') can also serve as vectors of disease agents, but not human malaria. Evolution The ancestors of ''Drosophila'' and the mosquitoes diverged . The culicine and ''Anopheles'' clades of mosquitoes diverged between and . The Old and New World ''Anopheles'' species subsequently diverged between and . '' Anophel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Simian Malaria
The simians, anthropoids, or higher primates are an infraorder (Simiiformes ) of primates containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders New World monkeys (Platyrrhini) and Catarrhini, the latter of which consists of the superfamilies Cercopithecidae (Old World monkeys in the stricter sense) and apes (Hominoidea; including the genus ''Homo''). The simians are sister group to the tarsiers (Tarsiiformes), together forming the haplorhines. The radiation occurred about 60 million years ago (during the Cenozoic era); 40 million years ago, simians colonized South America, giving rise to the New World monkeys. The remaining simians (catarrhines) split about 25 million years ago into Cercopithecidae and apes (including humans). Taxonomy and evolution In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as simians or anthropoids – were grouped under Anthropoidea (; ), whi ...

Filariasis
Filariasis is a parasitic disease caused by an infection with roundworms of the Filarioidea type. These are spread by blood-feeding insects such as black flies and mosquitoes. They belong to the group of diseases called helminthiases. These parasites exist in the wild in subtropical parts of southern Asia, Africa, the South Pacific, and parts of South America. One does not acquire them in temperate areas like Europe or the United States. Eight known filarial worms have humans as a definitive host. These are divided into three groups according to the part of the body they affect: * Lymphatic filariasis is caused by the worms ''Wuchereria bancrofti'', ''Brugia malayi'', and ''Brugia timori''. These worms occupy the lymphatic system, including the lymph nodes; in chronic cases, these worms lead to the syndrome of ''elephantiasis''. * Subcutaneous filariasis is caused by ''Loa loa'' (the eye worm), ''Mansonella streptocerca'', and ''Onchocerca volvulus''. These worms occupy the la ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
