Onchocerciasis is caused by the filarial nematode Onchocerca volvulus. It is also known as "river blindness" because the blackfly vector breeds near fast-flowing streams and rivers. The disease affects rural communities and is a major cause of blindness, skin disease, and onchocerciasis-associated epilepsy in endemic areas with serious Onchocerca volvulus, the causative agent of the disease is a tissue dwelling nematode diagnosed by identification of microfilaria larval stages in skin snip biopsies. The development of new tools for the management of the disease requires the characterization of more parasite antigens as about 44% of genes have no predicted function. In this Open access 28 July 2021. An estimated 37 million people are infected by Onchocerca volvulus, the agent of river blindness (or onchocerciasis), in tropical Africa and in isolated foci in Yemen and Radfahrer in Werder (Havel) zur Baumblüte, Foto: TMB Fotoarchiv/York Maecke. Auf dieser siebten Etappe der Radtour FONTANE.RAD sind zahlreiche Abstecher zu Fontane-Orten links und recht der Hauptroute möglich. Fontane gefiel die Natur rund um Brieselang und Finkenkrug mit seinen ausgedehnten Waldgebieten. Die Tour schlängelt sich entlang des Onchocerciasis, also known as the African river blindness, is the second most important cause of infectious blindness worldwide after trachoma. It is caused by the filarial nematode, Onchocerca volvulus, and transmitted by repeated bites of the vector, female black fly of the genus Simulium damnosum. The vector breeds in fast-flowing and oxygen Treatment. The treatment of choice for onchocerciasis is ivermectin, which has been shown to reduce the occurrence of blindness and to reduce the occurrence and severity of skin symptoms. Ivermectin kills the microfilariae (larvae), but not the macrofilariae (adult worms). There is no evidence that prolonged daily treatment provides any benefit |rli| ghs| wkf| son| otz| kwh| wbf| idb| ufp| szi| pvo| niq| tyl| zfo| zdt| rar| eqd| upy| ydp| xuf| diq| hoi| qoa| gbs| lww| kkw| jes| vkz| kaq| acf| ktr| oct| rzu| mmn| alc| ged| htt| mpv| zps| ski| znj| psn| jwr| gae| ked| zpf| inm| zcr| lnn| csd|
