Mansonella Perstans
''Mansonella perstans'' is a filarial (arthropod-borne) nematode (roundworm), transmitted by tiny blood-sucking flies called midges. ''Mansonella perstans'' is one of two filarial nematodes that causes serous cavity filariasis in humans. The other filarial nematode is '' Mansonella ozzardi''. ''M. perstans'' is widespread in many parts of sub-Saharan Africa, parts of Central and South America, and the Caribbean. Compared to infections with other filarial parasites such as ''Wuchereria bancrofti'', ''Brugia malayi'', and ''Loa loa'', ''Mansonella'' infections are relatively mild. However, the pathogenicity of ''M. perstans'' infection has been recently reconsidered in various studies. These studies have demonstrated that ''M. perstans'' has the ability to induce a variety of clinical features, including angioedema Calabar-like swellings, pruritus, fever, headache, eosinophilia, and abdominal pain. The overall disability among populations in regions where filariae are endemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mansonella Ozzardi
''Mansonella ozzardi'' is a filarial (arthropod-borne) nematode (roundworm). This filarial nematode is one of two that causes serous cavity filariasis in humans. The other filarial nematode that causes it in humans is ''Mansonella perstans''. ''M. ozzardi'' is an endoparasite that inhabits the serous cavity of the abdomen in the human host. It lives within the mesenteries, peritoneum, and in the subcutaneous tissue. Morphology Like other nematodes, ''M. ozzardi'' is a cylindrical and bilaterally symmetrical worm, with a pseudocoel, or a false body cavity. The exterior of the parasite, the cuticle, is a protective layer that can withstand the harsh environment in the digestive tracts of the human hosts. ''M. ozzardi'' and other nematodes have longitudinal muscles that run along the body wall. They also have dorsal, ventral, and longitudinal nerve cords connected to these longitudinal muscles. In the adult stages of ''M. ozzardi'', the females are larger than the males. ''M. o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mansonelliasis
Mansonelliasis is the condition of infection by the nematode ''Mansonella''. The disease exists in Africa and tropical Americas, spread by biting midges or blackflies. It is usually asymptomatic. Symptoms and signs Infections by ''Mansonella perstans'', while often asymptomatic, can be associated with angioedema, pruritus, fever, headaches, arthralgias, and neurologic manifestations. ''Mansonella streptocerca'' can manifest on the skin via pruritus, papular eruptions and pigmentation changes. '' Mansonella ozzardi'' can cause symptoms that include arthralgias, headaches, fever, pulmonary symptoms, adenopathy, hepatomegaly, and pruritus. Eosinophilia is often prominent but do not occur in all cases of Mansonelliasis. ''M. perstans'' can also present with Calabar-like swellings, hives, and a condition known as Kampala, or Ugandan eye worm. This occurs when adult M. perstans invades the conjunctiva or periorbital connective tissues in the eye. ''M. perstans'' can also present with h ...

Mansonella Streptocerca
''Mansonella streptocerca'', (formerly ''Diptalonema streptocerca''), is a filarial (arthropod-borne) nematode (roundworm) causing the disease streptocerciasis. It is a common parasite in the skin of humans in the rain forests of Africa, where it is thought to be a parasite of chimpanzees, as well. ''Mansonella streptocerca'' is one of three filarial nematodes that cause subcutaneous filariasis in humans. The other two filarial nematodes are ''Loa loa'' (the African eye worm), and ''Onchocerca volvulus'' (river blindness). The worm is distributed across West and Central Africa. Life cycle The contraction of an ''M. streptocerca'' infection can be better understood through an understanding of its life cycle. The life cycle involves two stages: one involving a midge (genus ''Culicoides'') and another involving a human host. First, a midge ingests a blood meal from a human host. This allows third-stage filarial larvae to enter the bite wound. Once inside the dermis, the larva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Onchocercidae are a family of nematodes in the superfamily Filarioidea. This family includes some of the most devastating human parasitic diseases, such as lymphatic filariasis, onchocerciasis, loiasis, and other filariases.

Patrick Manson
Sir Patrick Manson (3 October 1844 – 9 April 1922) was a Scottish physician who made important discoveries in parasitology, and was a founder of the field of tropical medicine. He graduated from University of Aberdeen with degrees in Master of Surgery, Doctor of Medicine and Doctor of Law. His medical career spanned Taiwan, China, Hong Kong, and London. He discovered that filariasis in humans is transmitted by mosquitoes. This is the foundation of modern tropical medicine, and he is recognized with an epithet "Father of Tropical Medicine". His discovery directly invoked the mosquito-malaria theory, which became the foundation in malariology. He eventually became the first President of the Royal Society of Tropical Medicine and Hygiene. He founded the Hong Kong College of Medicine for Chinese (subsequently absorbed into the University of Hong Kong) and the London School of Hygiene & Tropical Medicine. Manson was inflicted with gout during his service in China. His recurring c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
