ABSTRACT
Investigations of microbiota within mosquitoes continue to widen the spectrum of possible symbiont-based applications against vector-borne diseases. In this context, α-proteobacteria of the genus Asaia (Rhodospirillales Acetobacteraceae) are emerging as possible endosymbiotic candidates, particularly in paratransgenic approaches aimed at interrupting pathogen transmission. Previous studies have shown that Asaia spp. distribution among Anopheles gambiae and Anopheles stephensi (Diptera Culicidae) mosquitoes displayed positive rates of infection in isolated midguts, salivary glands and reproductive tissues. Similarly, Asaia has been detected in Aedes albopictus (Stegomyia albopicta) and Aedes aegypti (Stegomyia aegypti) (Diptera Culicidae) populations. Within the Culex pipiens complex (Diptera Culicidae), Asaia infection is still largely unexplored. Here, we summarize a preliminary survey of laboratory-reared Cx. pipiens complex and field-collected Culex quinquefasciatus for the presence of Asaia spp., and present the first identification of Asaia in some of the members of the Cx. pipiens complex and the first description in West African populations of Cx. quinquefasciatus.
