Recently, Wolbachia infection has been described in leishmaniasis vector sandflies. This endosymbiont bacterium is present in 60% of insects, and has been suggested as a mechanism of biological control of vector insects, because it causes a series of changes in the invertebrate host. In addition, recent studies have shown that this bacterium can prevent the development of parasites in vector insects. In this context, the present study aims to molecularly characterize the circulating strain of this bacterium in sandflies in the State of Bahia, Brazil, as well as the natural infection rate of Leishmania sp., and to evaluate the coinfection between Wolbachia and Leishmania. Seven hundred and forty-five (745) specimens of sandflies were collected in nine municipalities of Bahia, belonging to two species, Lutzomyia longipalpis (Lutz and Neiva, 1912) and Nyssomyia whitmani (Antunes and Coutinho, 1939). The results confirm infection by the protozoan Leishmania infantum and Wolbachia in both species collected. The identified strain of Wolbachia in sandflies was wStv MI, known to lead to a phenotype of cytoplasmic incompatibility in vector insects.
