Project context and summary:

The main objective of the project will be to study the impact of exposure to antibiotics of immature stages of Ae. aegypti on the microbiota of mosquito adults and on the transmission of arboviruses. More specifically, it will involve: (i) measuring the intensity of transfer of antibiotic-resistant Serratia marcescens from aquatic environment into mosquito larvae, (ii) assessing their persistence at different immature stages (larvae 1-4, pupae) and at the adult stage by detecting them in two mosquito organs (midgut and salivary glands), and (iii) testing the vector competence of adults exposed to AMR bacteria for dengue virus and chikungunya virus. We need to sequence the 16S gene in various samples (breeding site water, larvae and adult).
