In addition, bancroftian filariasis, mansonellosis and loiasis are all widespread and endemic in both parts of the basin (3,9-11).
Mansonellosis in the Upper Imo River Basin, Nigeria.
Endemic mansonellosis in Emohua Local Government Area, Nigeria: human parasitaemia and Culicoides biting patterns.
Part one, Diseases Transmitted by Arthropods, with 19 chapters is further divided in four sections: Arboviruses (Flavivirus, Togavirus, and Bunyavirus); Bacteria (Pests and Tularemia, Rickettsia, Borreliosis, Ehrlichiosis, Anaplasmo sis); Protozoa (Leishmaniasis, Chagas Disease, Other Trypanosomiasis, Malaria, Babesiosis, Theileriosis, Hepatozoonosis); and Helminths (Lymphatic Filariasis, Onchocerciasis, Mansonellosis
The presence of endemic onchocerciasis, mansonellosis
, and loaiasis in our study area could explain this disparity.
Mansonellosis is the most widespread filarial infection of man in Nigeria (1,2).
Although mansonellosis has been reported from the forest belt of Nigeria (2,10-12), none of these works included entomological investigations.
