Abstract:

Les arbovirus (virus transmis par des arthropodes) sont à l'origine de maladies humaines telles que la dengue, le chikungunya ou encore le Zika. Le moustique Aedes aegypti, est le vecteur majeur de ces trois arbovirus. La faible efficacité des méthodes de contrôle des populations de moustiques, principalement réalisées au moyen d'insecticides chimiques ouvre un champ de développement de nouvelles approches en lutte antivectorielle. Le moustique, hôte vecteur, contrôle la réplication virale en limitant les réponses immunitaires antivirales. La machinerie RNA interférence (RNAi) est la voie joua

Las enfermedades transmitidas por mosquitos (ETM) son una creciente preocupación para la salud pública mundial. El aumento de las actividades humanas a escala internacional y el calentamiento global han permitido la rápida difusión y establecimiento de las especies invasoras de mosquitos en nuevas áreas geográficas. Además, la globalización facilita la introducción de arbovirus exóticos en áreas naïve, donde el mosquito está presente, incrementando la probabilidad de los brotes de ETM. Los brotes de ETM, especialmente aquellos causados por arbovirus como el virus del Dengue, el virus del Zika

Abstract:

Arthropod-borne viruses, arboviruses, have the ability to replicate in both vertebrates and invertebrates and are transmitted to susceptible vertebrate hosts by vectors such as mosquitoes and ticks. Ticks are important vectors of many highly pathogenic arboviruses, including the flavivirus tick-borne encephalitis virus (TBEV) and the nairovirus Crimean-Congo haemorrhagic fever virus. In contrast, alphaviruses are principally mosquito-borne and have been isolated only rarely from ticks; ticks have not been implicated as their vectors. Nevertheless, the alphavirus Semliki Forest virus (SFV) repl

Developing vaccine strains of these viruses that cannot infect, or be transmitted by, mosquito vectors would be useful tools to block virus transmission cycles in their vectors.

Arboviruses are transmitted between vertebrate hosts by arthropod vectors, such as mosquitoes or ticks. In vertebrates arboviruses cause cytopathic effects and disease, however, arbovirus infection of arthropods usually results in persistence. Control of arboviral infection is mediated by the arthropod’s immune system. Pathways such as RNAi, JAK/STAT, Toll and IMD have previously been implicated in controlling arbovirus infections. In contrast, the antiviral role of other pathways in mosquitoes, such as melanisation, is unknown. Using high through output 454 sequencing the transcriptome of U4.

Abstract:

acase@tulane.edu<br>Urban epidemics of mosquito-borne diseases are driven by a close association between mosquito vectors and artificial container habitats near residences. In New Orleans, Louisiana abundant populations of the mosquito species Aedes (Stegomyia) aegypti (Linnaeus) and Aedes (Stegomyia) albopictus (Skuse) (Diptera: Culicidae), are potentially capable of supporting local transmission of viruses such as dengue, chikungunya and Zika introduced by infected individuals. Container-inhabiting Aedes mosquito populations are focally abundant, and unevenly distributed across the urban lan

Abstract:

Background: Mosquito-borne diseases are a growing concern for temperate regions including the northeastern US. There the two primary mosquito vectors, Cx. pipiens and Ae. albopictus are widespread, endemic circulation of West Nile virus causes sporadic outbreaks, and imported arboviruses such as dengue, chikungunya, and Zika are on the rise. With temperate mosquito-borne disease outbreaks likely to increase in frequency, it is critical to reduce mosquito populations in the northeastern US. Community-based source reduction is heralded as the most sustainable component of integrated mosquito man

Abstract:

Arboviruses are blood-borne pathogens that threaten half of the world’s population. The recent outbreak of Zika virus (ZIKV) in Brazil has highlighted the importance of developing new strategies to limit virus spread. While vaccines are in development, one way to immediately suppress viral transmission is through biocontrol of mosquito vector. Novel biocontrol strategies utilize microbe – mosquito interactions to inhibit the transmission of pathogens. A powerful tool under investigation is the intracellular bacteria, Wolbachia pipientis, which are maintained in insect populations through mater
