Abordagem molecular no diagnostico laboratorial da filaria linfática: Wuchereria bancrofti

Transmission of Wuchereria Bancrofti

me about the mode of transmission of Wuchereria bancrojti. I understood that it was through the bite of an infected mosquito (Culex) larva passing through the bite puncture though capable of penetrating the healthy skin. I have just read in the ' Science and Practice of, Surgery', 1948 ed. (vol. I, p. 258) by Romanis and Mitchiner, that the infection is through drinking water in which the bodie...

Lectin-binding characteristics of Wuchereria bancrofti microfilariae.

The binding of 10 different lectins to the surface of microfilariae of Wuchereria bancrofti has been investigated. Wheat germ agglutinin (WGA) and Helix pomatia lectin (HPA) bound specifically to the sheathed microfilariae indicating the presence of N-acetyl-D-glucosamine and N-acetyl-D-galactosamine respectively on the surface. Exsheathed microfilariae did not react with any of the lectins. Tr...

An unusual presentation of Wuchereria bancrofti infection.

Prevalence of Wuchereria bancrofti in Georgetown, Guyana1

A random sample bloodsmear survey was conducted during evening hours in Georgetown, Guyana, to determine the prevalence of Wuchereria bancrofti microfilariae. In all, 182 of 2,818 persons tested (6.5%) yielded positive results-indicating that the overall prevalence of Bancroffian filariasis has not diminished and may be on the rise. Relatively high prevalences found in children and adolescents ...

Immunoepidemiology of Wuchereria bancrofti infection: parasite transmission intensity, filaria-specific antibodies, and host immunity in two East African communities.

We compared the age profiles of infection and specific antibody intensities in two communities with different transmission levels in East Africa to examine the contribution of humoral responses to human immunity to the vector-borne helminth Wuchereria bancrofti. The worm intensities were higher and exhibited a nonlinear age pattern in a high-transmission community, Masaika, in contrast to the l...
