Onchocerca–Simulium complexes in Venezuela: can human onchocerciasis spread outside its present endemic areas?

Autor: H. Frontado, M. G. Basáñez, N. J. Villamizar, L. Yarzábal

Publikováno v: Parasitology. 120:143-160

The compatibility between sympatric and allopatric combinations of Onchocerca volvulus–anthropophilic species of Simulium was studied in the north-eastern focus of human onchocerciasis as well as in a densely populated locality of the Amazonas Stat

Density-dependent processes in the transmission of human onchocerciasis: relationship between microfilarial intake and mortality of the simuliid vector

Autor: H. Frontado, Harold Townson, N. J. Villamizar, María-Gloria Basáñez, Roy M. Anderson, J. R. Williams

Publikováno v: Parasitology. 113:331-355

SUMMARYIn order to construct an analytical model of onchocerciasis transmission, it is necessary to elucidate the functional relationships of the various population rate processes taking place within the human and vector hosts. Two previous papers ha

Autor: Jane Davies, N. J. Villamizar, H. Frontado, M. G. Basáñez, J. N. Raybould, I. Petralanda

Publikováno v: Medical and veterinary entomology. 14(3)

Summary Phosphoglucomutase (PGM) and trehalase (Tre) isoenzymes of five species of Simulium blackflies (Diptera: Simuliidae), vectors of onchocerciasis in Venezuela, were investigated by means of a portable electrophoresis field kit. Tre differed bet

Density-dependent processes in the transmission of human onchocerciasis: Intensity of microfilariae in the skin and their uptake by the simuliid host

Autor: J. Prod'hon, Graham F. Medley, N. J. Villamizar, H. Frontado, M. G. Basáñez, Roy M. Anderson, Michel Boussinesq

Publikováno v: Scopus-Elsevier

SUMMARYThe transmission success of Onchocerca volvulus is thought to be influenced by a variety of regulatory or density-dependent processes that act at various points in the two-host life-cycle. This paper examines one component of the life-cycle, n
