Leishmania Turanica
''Leishmania'' is a parasitic protozoan, a single-celled organism of the genus ''Leishmania'' that are responsible for the disease leishmaniasis. They are spread by sandflies of the genus ''Phlebotomus'' in the Old World, and of the genus ''Lutzomyia'' in the New World. At least 93 sandfly species are proven or probable vectors worldwide.WHO (2010) Annual report. Geneva Their primary hosts are vertebrates; ''Leishmania'' commonly infects hyraxes, canids, rodents, and humans. History Members of an ancient genus of the ''Leishmania'' parasite, ''Paleoleishmania'', have been detected in fossilized sand flies dating back to the early Cretaceous period. The first written reference to the conspicuous symptoms of cutaneous leishmaniasis surfaced in the Paleotropics within oriental texts dating back to the 7th century BC (allegedly transcribed from sources several hundred years older, between 1500 and 2000 BC). Due to its broad and persistent prevalence throughout antiquity as a myster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ronald Ross
Sir Ronald Ross (13 May 1857 – 16 September 1932) was a British medical doctor who received the Nobel Prize for Physiology or Medicine in 1902 for his work on the transmission of malaria, becoming the first British Nobel laureate, and the first born outside Europe. His discovery of the malarial parasite in the gastrointestinal tract of a mosquito in 1897 proved that malaria was transmitted by mosquitoes, and laid the foundation for the method of combating the disease. Ross was a polymath, writing a number of poems, published several novels, and composed songs. He was also an amateur artist and mathematician. He worked in the Indian Medical Service for 25 years. It was during his service that he made the groundbreaking medical discovery. After resigning from his service in India, he joined the faculty of Liverpool School of Tropical Medicine, and continued as Professor and Chairman of Tropical Medicine of the institute for 10 years. In 1926, he became Director-in-Chief of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leishmania Major
''Leishmania major'' is a species of parasite found in the genus ''Leishmania'', and is associated with the disease zoonotic cutaneous leishmaniasis (also known as Aleppo boil, Baghdad boil, Bay sore, Biskra button, Chiclero ulcer, Delhi boil, Kandahar sore, Lahore sore, Oriental sore, Pian bois, and Uta). ''L. major'' is an intracellular pathogen which infects the macrophages and dendritic cells of the immune system. Though ''Leishmania'' species are found on every continent aside from Antarctica, ''Leishmania major'' is found only in the Eastern Hemisphere, specifically in Northern Africa, the Middle East, Northwestern China, and Northwestern India. Biology Life cycle As a trypanosomatid, ''L. major'' begins its lifecycle in amastigote form in the midgut of the main vector, female sand flies ('' Phlebotomus spp.''). Once in the gut of the sand fly, the parasites change from aflagelated amastigotes into flagellated promastigotes for 1–2 weeks until they are fully develop ...

Leishmania Tropica
''Leishmania tropica'' is a flagellate parasite and the cause of anthroponotic cutaneous leishmaniasis in humans. This parasite is restricted to Afro-Eurasia and is a common cause of infection in Afghanistan, Iran, Syria, Yemen, Algeria, Morocco, and northern India. History The first description of ''Leishmania tropica'' was done in 1903 by James Homer Wright, an American pathologist. In 1914, it was suggested that ''L. tropica'' should be divided into two subspecies, namely ''L. tropica minor'' and ''L. tropica major'', based on the size of the parasites found in skin lesions. Later, these two subspecies turned out to be epidemiologically different and were correlated to different types of lesions. ''L. tropica minor'' causes dry nodular lesions in urban environments, while ''L. tropica major'' causes wet ulcerating lesions in rural regions. Bray et al. therefore proposed in 1973 that the subspecies should be considered as two separate species, ''L. tropica major'' became '' ...
