| Mansonella demarquayi | A filarial parasite occurring in 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. Synonym: Mansonella demarquayi, Mansonella tucumana. (05 Mar 2000) |
