Since its inception, the Institut Pasteur has located near pandemic areas. The first Institut Pasteur outside of France was created in 1891 in Saigon in Vietnam to vaccinate people against rabies and smallpox.
This proximity to sites of infection offers a real capacity of reaction and analysis to the Network. Present on five continents through 33 Institutes, it is recognized as a specialist in microbiological surveillance.
Researchers, men and women of different cultures are united by the same Pastorian culture, the same scientific rigor and the same values.

Thus, the Network institutes contribute to the prevention and treatment of infectious diseases by:


Research activities focusing on the main transmissible bacterial, parasitic or viral diseases. Special relationships with the laboratories of other institutes belonging to the Network create a link between local concerns and the international scientific community. They also enable technology transfer and the implementation of leading-edge biological methods in environments which would otherwise be unable to have access to such developments

Public health activities : national reference centers and WHO collaborating centers, participation in national programs to fight against infectious diseases ... These activities also include field investigations, backed by the operation of the laboratories that then process numerous organic samples. These are essential for an accurate understanding of the environment and the epidemiological mechanisms of disease.
Service activities : clinical chemistry, microbiology of water and food, testing centers, centers for vaccinations ...

Training activities, not only to personnel Institutes but also to external staff, technicians or students, who may then use their experience in other regional or national or bodies.

The Network's activities are divided across these three Pasteurian missions, with a focus on:

  • Major diseases with epidemic potential (HIV / AIDS, tuberculosis, malaria ...)
  • Upstream research for new vaccines and therapies
  • Emerging diseases (dengue fever, encephalitis, hemorrhagic fever, chikungunya ...)
  • Security health activities (surveillance and outbreaks intervention)
  • Surveillance and research on resistance to anti-infective
  • Neglected diseases (rabies, diarrhea, leishmaniasis ...)

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 transmit the local Zika virus


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.
