“…The transmission of the disease in a given focus requires thus the coexistence of an adequate number of vectors around the parasite reservoir. Consequently, the risk is elevated around an infected individual, like in the case of a dog that lives in the neighbourhood of a phlebotomine-favourable niche, and gradually decreases when moving away from this source of parasites [27], [28]. In accordance with the literature, our working hypothesis was that the vector species (one or more) should belong to the genus Phlebotomus.…”

BackgroundDifferent epidemiological studies previously indicated that canine leishmaniasis is present in the region of Thiès (Senegal). However, the risks to human health, the transmission cycle and particularly the implicated vectors are unknown.Methodology/Principal FindingsTo improve our knowledge on the population of phlebotomine sand flies and the potential vectors of canine leishmaniasis, sand flies were collected using sticky traps, light traps and indoor spraying method using pyrethroid insecticides in 16 villages of the rural community of Mont Rolland (Thiès region) between March and July 2005. The 3788 phlebotomine sand flies we collected (2044 males, 1744 females) were distributed among 9 species of which 2 belonged to the genus Phlebotomus: P. duboscqi (vector of cutaneous leishmaniasis in Senegal) and P. rodhaini. The other species belonged to the genus Sergentomyia: S. adleri, S. clydei, S. antennata, S. buxtoni, S. dubia, S. schwetzi and S. magna. The number of individuals and the species composition differed according to the type of trap, suggesting variable, species-related degrees of endophily or exophily. The two species of the genus Phlebotomus were markedly under-represented in comparison to the species of the genus Sergentomyia. This study also shows a heterogeneous spatial distribution within the rural community that could be explained by the different ecosystems and particularly the soil characteristics of this community. Finally, the presence of the S. dubia species appeared to be significantly associated with canine leishmaniasis seroprevalence in dogs.Conclusions/SignificanceOur data allow us to hypothesize that the species of the genus Sergentomyia and particularly the species S. dubia and S. schwetzi might be capable of transmitting canine leishmaniasis. These results challenge the dogma that leishmaniasis is exclusively transmitted by species of the genus Phlebotomus in the Old World. This hypothesis should be more thoroughly evaluated.

“…Most surveys of sandflies in the département have been confined to areas where enzootic canine leishmaniasis and/or cases of human VL have been recorded (Giacomo, 1978;Izri et al, 1992Izri et al, , 1994Izri et al, , 1996Izri, 1996). Only five species of sandfly have been recorded in Alpes-Maritimes and/or Monaco: Sergentomyia minuta (which does not bite man), Phlebotomus mascittii, P. perfiliewi, P. perniciosus and P. ariasi (Giacomo, 1978;Izri et al, 1992Izri et al, , 1994Izri et al, , 1996Izri, 1996). Phlebotomus perniciosus and P. ariasi are the main or sole vectors of L. infantum in Alpes-Maritimes, with P. perniciosus the main vector in peri-urban areas and P. ariasi only common in rural areas (Giacomo, 1978).…”

Health decision-makers working in Africa often need to act for millions of people over large geographical areas on little and uncertain information. Spatial statistical modelling and Bayesian inference have now been used to quantify the uncertainty in the predictions of a regional, environmental risk map for Loa loa (a map that is currently being used as an essential decision tool by the African Programme for Onchocerciasis Control). The methodology allows the expression of the probability that, given the data, a particular location does or does not exceed a predefined high-risk threshold for which a change in strategy for the delivery of the antihelmintic ivermectin is required.
