[Intake of microfilariae by the vector in the case of a low microfilareamia (author's transl)].

The study of the intake of microfilariae of Dipetalonema dessetae by Aedes aegypti leads to two conclusions with respect to the microfilaraemia: --there is no concentration of microfilariae in the uptake of blood by Aedes. --the microfilariae are nearly homogeneously distributed in the vertebrate host blood available to the vector for feeding. Such a distribution of microfilariae in the cutaneous blood supply of the host gives the maximum chance for a mosquito to become infected when taking a blood meal. In the pair Wuchereria bancrofti--Aedes polynesiensis the capacity of individuals with a low microfilaraemia to transmit infections seems to be related to a limitation phenomenon.
