Institut Pasteur International Network

The Institut Pasteur International Network (RIIP), associates 33 institutes around the world linked by the same missions and values. The foundation of RIIP resides in the sustainability of its structures, involvement of its researchers and strengthening of human resources. The RIIP allows scientists to become involved in research at the heart of endemic areas, to share their knowledge and expertise and also to invest in the development research group at 4 years.

Culex mosquitoes are experimentally unable to transmit Zika viru


We report that two laboratory colonies of Culex quinquefasciatus and Culex pipiens mosquitoes were experimentally unable to transmit ZIKV either up to 21 days post an infectious blood meal or up to 14 days post intrathoracic inoculation.

Infectious viral particles were detected in bodies, heads or saliva by a plaque forming unit assay on Vero cells. We therefore consider it unlikely that Culex mosquitoes are involved in the rapid spread of ZIKV.

Culex quinquefasciatus from Rio de Janeiro Is not competent to tTransmit the local Zika virus


The southern house mosquito Cx. quinquefasciatus from Rio de Janeiro was not competent to transmit local strains of ZIKV. Thus, there is no experimental evidence that Cx. Quinquefasciatus likely plays a role in the ZIKV transmission. Consequently, at least in Rio, mosquito control to reduce ZIKV transmission should remain focused on Ae. aegypti.
