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 plague, one of the most dangerous bacterial diseases for man, is currently reemerging in the world. Comparative genome work coordinated by researchers at Institut Pasteur and at Lawrence Livermore National Laboratory in the US, has shed light on the genetic bases that accompanied the emergence of the extremely virulent plague bacillus from a much less pathogenic ancestor, less than 20,000 years ago. These results, published in PNAS, also made it possible to identify specific genes of the plague bacillus that are choice targets for the future development of new diagnostics, treatments and vaccines against this blight.

With nearly 30,000 human cases declared over a period of about ten years, the plague is far from being a disease of the past, and is even currently reemerging in the world. Focuses still remain, not only in Africa, Asia and South America, but also in the United States, where a dozen human cases are reported each year on average. Concern related to this terrible disease has been heightened by the appearance of a strain with multiple resistance to antibiotics, discovered in 1995 by researchers at Institut Pasteur. The plague bacillus is also categorized among the most potentially dangerous agents of bioterrorism.
In 1999, the team led by Elisabeth Carniel at the Institut Pasteur, working in cooperation with the group led by Mark Achtman at the Max-Planck-Institut in Berlin, showed that the plague bacillus, Yersinia pestis, is a very recent descendant of Yersinia pseudotuberculosis, a much less virulent bacteria that causes gastrointestinal disorders.**
In collaboration with the group led by Emilio Garcia of Lawrence Livermore National Laboratory in the United States, Elisabeth Carniel’s team thus launched a sequencing program for the Yersinia pseudotuberculosis genome. The analysis of this genome, conducted by a consortium of French and American teams, and its comparison with that of Yersinia pestis, has made it possible to update a certain number of genes and metabolic processes that have diverged between the two species and that are potentially involved in the extreme virulence of the plague bacillus.
The researchers have thus discovered six chromosomal regions in Yersinia pestis that have been acquired by the bacillus when it diverged from Y. pseudotuberculosis, and have discovered the existence of many genes (representing over 13% of the genome studied) that were deactivated when it emerged less than 20,000 years ago. These modifications have resulted in the birth of one of the most feared pathogens in human history.
Researchers are now characterizing the genetic modifications at the root of the appearance of Yersinia pestis that might explain its exceptional virulence and its very particular clinical and epidemiological characteristics.
Aside from the fundamental knowledge that this study offers in terms of understanding the emergence of new diseases, it also creates possibilities for identifying new diagnostic, therapeutic and vaccination targets in order to more effectively fight the plague.
