Current Position

My project concerns the emergence of the mutated strain of CHIKV (E1-A226V) during the outbreak of 2011 in Congo (Brazzaville) in relation with the recent introduction and expansion of Ae. albopictus. As stated in East Africa where this mutation has emerged leading to a better transmission by Ae. albopictus, is this scenario applicable to West Africa?

TECHNICIAN

laurence.mousson@pasteur.fr

 

Current Position

My project is part of the FP7 DenFree project. The tasks where I am involved aim to examine the role of mosquito vectors in dengue emergence, with special emphasis on the European context. I will be implicated in evaluating the ability of European Aedes albopictus to transmit imported DENV strains (originated from DEN endemic regions, Thailand and Cambodia) and in identifying viral genetic changes after experimental alternating cycling to enhance potential of Ae. albopictus from southern France to transmit imported DEN strains from Southeast Asia.

karima.zouache@pasteur.fr

 

Current Position

My project is part of the FP7 Vectorie project on surveillance of two arthropod-borne diseases, West-Nile and Chikungunya, in Europe. Our laboratory is involved in defining the vector competence of Ae. albopictus mosquitoes from different European countries for CHIK virus at low temperatures. I am responsible of three main tasks which are: (i) experimentally challenges of field-collected European populations of Ae. albopictus (France, Italy, Montenegro) with different CHIKV isolates; (ii) evaluation of mosquito thermo-preference and (iii) effects of temperature on gene expression in temperate Ae. albopictus infected by different strains of CHIKV and submitted to thermal stress, using a transcriptomic approach provided by the technology of high throughput RNA sequencing.

Current Position

My project is part of the EMIDA project and concerns the risk for European mosquitoes to become a vector of the Rift Valley fever virus. To evaluate this risk, we have to investigate (i) the molecular identification of RVFV vectors (Ae. vexans complex and Cx. pipiens complex) with special focus on European counterparts of tropical mosquitoes species through the use of molecular tools and estimate the abundance and dynamics of potential RVFV vectors in Camargue (France); (ii) characterize the competence of potential European RVFV vectors in comparison with their African counterparts, and (iii) investigate through in vivo experiments if RVFV can be adapted to European mosquitoes.

Current Position

 

My PhD project aims to analyze the risk for CHIKV to emerge in Latin America, a continent where the typical CHIKV vectors Ae. aegypti and Ae. albopictus are present in high densities, and where several CHIKV importation cases have been reported. Until now, local CHIKV transmission has never been reported in Latin America. To assess this risk, I will: (i) evaluate the vector competence of different field-collected Aedes albopictus from Latin America to transmit several genotypes of CHIKV, (ii) study CHIKV evolution and adaptation to Latin American vectors using in vitro and in vivo systems and, (iii) trace the evolutionary history of Aedes albopictus using phylogenetic approaches.

Current Position

My research is a part of the European Union’s DENFREE project. With the recent autochthonous cases of dengue in France (2010), Croatia (2010) and in the Portuguese island of Madeira (2012), dengue has arrived in Europe. As an arbovirus, dengue virus (DENV) requires replication in both a vertebrate host and insect vector, and interactions between these two disparate hosts within a permissive environment determine the outcome of transmission. My main objectives are: (i) to select a DENV more adapted to be transmitted by European Aedes albopictus using serial passages, and (ii) to generate molecular clones of these adapted strains, allowing me to characterize the molecular mechanisms behind this adaptation. These studies will provide unique insights into viral-vector interactions and their impact on fitness in mammalian systems.

Post-doctoral fellow

celestine.atyame-nten@pasteur.fr

 

Current Position

My project aims to analyze the tripartite interactions between insecticide resistance genes, Wolbachia and arboviruses in mosquito vectors. The use of insecticides plays a key role in the prevention and control of vector-borne diseases. However, its efficacy has been challenged by the emergence of insecticide resistance. Mutations conferring insecticide resistance are often associated with a measurable fitness cost, suggesting the existence of resource-based trade-offs that could affect the replication of Wolbachia and pathogens. The overall goal of my project is to assess whether insecticide resistance genes can affect the transmission of Rift Valley Fever Virus (RVFV) and West Nile Virus (WNV) in the Culex pipiens mosquito. This goal will be achieved by pursuing four specific aims: (i) comparing vector competence of resistant and susceptible mosquitoes for RVFV and WNV, (ii) examining the effect of Wolbachia genetic groups and Cx. pipiens subspecies in the interactions between insecticide-resistance genes and RVFV and WNV, (iii) assessing the effect of temperature in these tripartite interactions, and (iv) exploring underlying genetic molecular mechanisms involved in the observed phenotypes. This project will provide a unique opportunity to know whether insecticide resistance genes may change the transmission of arboviruses by affecting the vector competence.

Current Position

My PhD project aims to analyze the antiviral ability of transgenic mosquitoes. We are currently generating several miRNA-based transgenic Aedes aegypti and Aedes albopictus designed to suppress the DENV and CHIKV replication in mosquitoes. To evaluate the possibility of applying this strategy into practical disease control, we will: (i) experimentally challenge the transgenic mosquitoes under different conditions, e.g. virus titers, incubation temperatures, and humidity to analyze the suppression efficiency on viral replication; (ii) test male mating competitiveness to acquire the fitness impact information among transgenic populations; (iii) develop a novel transgenic control strategy for arboviruses.
