Onchocerca Flexuosa
Onchocerca is a genus of parasitic roundworm. It contains one human parasite – ''Onchocerca volvulus'' – which is responsible for the neglected disease Onchocerciasis, also known as "river blindness" because the infected humans tend to live near rivers where host black flies live. Over 40 million people are infected in Africa, Central America, and South America. , Indiana State University. Accessed 14 February 2008.

Black Fly
A black fly or blackfly (sometimes called a buffalo gnat, turkey gnat, or white socks) is any member of the family Simuliidae of the Culicomorpha infraorder. It is related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 2,200 species of black flies have been formally named, of which 15 are extinct. They are divided into two subfamilies: Parasimuliinae contains only one genus and four species; Simuliinae contains all the rest. Over 1,800 of the species belong to the genus ''Simulium''. Most black flies gain nourishment by feeding on the blood of mammals, including humans, although the males feed mainly on nectar. They are usually small, black or gray, with short legs, and antennae. They are a common nuisance for humans, and many U.S. states have programs to suppress the black fly population. They spread several diseases, including river blindness in Africa (''Simulium damnosum'' and ''S. neavei'') and the Americas (''S. callidum'' and ''S. metallicum'' in Central Am ...

Parasitic Nematodes Of Mammals
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onchocerca Tubingensis
''Onchocerca tubingensis'' is the name of a nematode. It was discovered in 1974 and published by O. Bain und H. Schulz-Key in ''Tropenmedizin und Parasitologie'' and named after Tübingen. Red deer (''Cervus elaphus'') are the host of this parasite. The adult worms of Onchocerca tubingensis are found in subcutaneous nodules on the caudal part of the back, while the microfilariae are distributed on the ventral part of the body with maximum densities in the region of the sternum The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Sh ... and with lower densities on the inner sides of the hindlegs. The infection rates of 94 red deer investigated in southern Germany during 1907–1974 were 23%.

Onchocerca Lupi
''Onchocerca lupi'' is a nematode that causes ocular onchocerciasis, an eye disease, in canines and felines. The parasite was first described in 1967 in a wolf from Georgia. The other ''Onchocerca'' spp., '' O. volvulus'', is a human parasite that causes ocular onchocerciasis in human and affects 37 million people globally.Otranto, Domenico, et al. "Human ocular filariasis: further evidence on the zoonotic role of Onchocerca lupi." ''Parasit Vectors'' 5.1 (2012): 84. The male ''O. lupi'' worms are smaller in size than the females. Males are 43–50 mm in length and 120-200 µm in diameter. Females are 275-420 µm in diameter but the total length are unknown while the longest fragments recorded were 160–165 mm. They both are fragile and slender. Life cycle The complete life cycle of ''O. lupi'' is still unknown. The black fly, ''Simulium tribulatum'', is reported as a putative vector.
