Mansonella ozzardi(redirected from Mansonella tucumana)
a filarial parasite occurring in the Yucatan, Panama, Colombia, northern Argentina, Guyana, French Guiana, and the islands of St. Vincent and Dominica, causing mansonelliasis; the microfilariae are not ensheathed, and there are no nuclei in the pointed tail; the life cycle is similar to that of Wuchereria bancrofti; humans are the only known definitive host, and the intermediate hosts are biting midges, Culicoides furens and possibly C. paraensis.
a parasitic worm that is indigenous to much of Latin America and the Caribbean islands. It is a relatively benign nematode that infects humans, sometimes causing hydrocele or lymphadenopathy. The larvae live in the bloodstream, and adult worms are found in the visceral mesenteries. The intermediate hosts are biting flies of the genus Culicoides.
Mansonella ozzardiA filarial nematode which causes serosal filariasis in humans.
Subsaharan Africa, Central and South America, Caribbean; up to 50% of Brazilian farmers are infected by M ozzardi.
Haematophagous midges (genus Culicoides) in the Caribbean and blackflies (genus Simulium) in the Amazon basin.
Generally banal, with angioedema, Calabar-like swellings, pruritus, fever, headache, eosinophilia and abdominal pain.
Uncertain; anti-filarial drugs (e.g., ivermectin, diethylcarbamazine and albendazole) are ineffective against Mansonella species.
a genus of nematode parasites of the superfamily Filaroidea transmitted by Culicoides and Simulium spp.
a species found in the mesentery and visceral fat of humans in Central and South America; suspected sightings also in domestic animals.
