Previous studies on lymphatic filariasis in Mali showed high infection rate in rural area. This study was aimed to find Wuchereria bancrofti microfilaria in human peripheral blood and larvae in vectors. For that purpose we carried out an entomological, clinical and parasitological study in Banambani a village located at 25 km from Bamako the capital city. The parasitological and clinical study was a single cross sectional study including night blood thick smear and physical examination. The entomological study was longitudinal with three annual surveys at the beginning, the middle and the end of the rainy season with parasite detection on vector by PCR. The infection rates by night thick smear was 1.5% of the study sample. The transmission was assured by Anopheles gambiae s.l and Anopheles funestus. Wuchereria bancrofti larvae have been detected on 0.5% of the vectors. The higher entomological inoculation rate (EIR) for An. gambiae s.l has been observed in August (4.03 infective bites per man per night) and in October for An. funestus (1.9 infective bites per man per night). Lymphatic filariasis is present in Malian rural area and transmission still occurring.
