The Pasteur Museum is housed in the apartment where Louis Pasteur spent his final seven years and offers a rare behind-the-scenes look at the living and working environment of the world-renowned scientist. Visitors can gain a unique insight into his everyday life alongside his wife and can admire his rich and diverse scientific work.
The Institut Pasteur’s scientific strategy focuses on developing original and innovative topics and promoting interdisciplinary and multidisciplinary cooperation and approaches. The Institut Pasteur teams have access to the technological resources needed to speed up and further improve the quality of their outstanding research.
Ever since the introduction of the world’s first "Technical Microbiology" course in 1889, teaching has been a priority for the Institut Pasteur. The Institut Pasteur has an international reputation for quality teaching that attracts students from all over the world who come to further their training or top up their degree programs.
The mission of the Industrial Partnership team is to detect, promote, assist and protect the inventive activities from research (inventions, know-how and biological materials) conducted at the Institut Pasteur (and in some Institutes of its international network), and transfer there to industrial and/or institutional partners, in order to serve the patient needs and for the benefit of the society, as well as to contribute to sustainability of the Institut Pasteur’s resources.
With international courses, PhD and postdoctoral traineeship, each institute of the Institut Pasteur International Network (RIIP) contributes to the transmission of knowledge with the training of young researchers all around the world. In this context, doctoral and postdoctoral programmes, study and traineeship fellowships are available to scientists. Alongside training, dynamism and attractiveness of RIIP will result in the creation of 4-year group for the young researchers.
The mother-to-child transmission of Chikungunya virus established
The mother-to-child transmission of Chikungunya virus established
During a vast prospective study among pregnant women, clinicians in Reunion and researchers from the Institut Pasteur and Inserm demonstrated for the first time the maternal-fetal transmission of Chikungunya virus. Their findings show that this transmission almost exclusively occurs when mothers are infected shortly before term and that newborns have an increased probability of developing a severe form of the disease.
Paris, april 18, 2008
The Chikungunya epidemic prevailing in the Indian Ocean since the end of 2004 reached Reunion Island. Up to December 2006, it affected more than one third of the population of the island. In June 2005, the first case suggesting possible mother-to-child transmission of the virus was observed in the South Reunion Hospital Group (GHSR).
In order to explain the onset of the disease in newborns unexposed to bites of the mosquito vectors, GHSR doctors, including Patrick Gérardin, Alain Michault, Georges Barau and Pierre-Yves Robillard, the team of Marc Lecuit1 (Institut Pasteur /Avenir Inserm U604) and Isabelle Schuffenecker (National Arbovirus Reference Centre, Institut Pasteur), rapidly joined forces, in collaboration with other researchers at the Pasteur Institute, to find out if and how mother-to-child transmission of Chikungunya takes place and to determine its incidence, seriousness and mechanism. A vast multidisciplinary prospective study was therefore set up among pregnant women admitted to the GHSR.
Doctors and scientists carried out 22 months of clinical investigations in more than 7,500 pregnant women including 678 who were infected during their pregnancy. They found that the closer to term a mother contracted the infection, the more likely she was to transmit the virus to her child. Hence, although globally less than 3% of children born of mothers who developed Chikungunya during their pregnancy were contaminated, the transmission was almost exclusivel observed when the mother is infected during the two days before childbirth, with a transmission rate reaching 50% in this instance. The study also showed that in one case out of two, children who contracted Chikungunya by maternal-fetal transmission develop a severe form of the disease, with encephalopathy resulting in cerebral oedema in particular, and sometimes haemorrhagic complications.
These results show the importance of follow-up during pregnancy in areas where Chikungunya is endemic and the high probability of transmission of the virus to the infant if the mother is ill during childbirth. They also raise the alarm about the danger of this disease in certain high risk populations such as newborns, and stress that mother-child transmission of the virus should now be taken into account by the public Health Authorities.
