  The main vectors of Zika virus are Aedes aegypti mosquitoes. Aedes albopictus mosquitoes were found to be competent in laboratory experiments. Within the context of the possible emergence of this virus in Europe, […]

Despite intensive research efforts on arthropod-borne viruses (arboviruses), many aspects related to immunological consequences of arthropod vector-derived salivary factors are unknown, especially those occurring at the injection site. During a blood meal, arboviruses are […]

Groupe Arbovirus (GA) de l’Unité Environnement et Risques Infectieux a été créé en 2014. Le GA travaille sur les virus transmis par les arthropodes (Arbovirus), avec un intérêt pour les arbovirus émergents ou réémergents […]
