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.
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.
TB transmission: Why tubercle bacilli of animal origin don't spread within human populations
July 22, 2014
Research teams led by Christophe Guilhot of the Institute of Pharmacology and Structural Biology (CNRS / Paul Sabatier University - Toulouse) and Roland Brosch of the Institut Pasteur, in collaboration with the team led by Carlos Martin of the University of Zaragoza (Spain), examined the mechanisms involved in tuberculosis (TB) transmission to explain why tubercle bacilli of animal origin don't spread within human populations. Their work, published on July 21, 2014 in the journal PNAS, opens up new possibilities for understanding the functions and mechanisms involved in TB transmission in humans and could eventually lead to therapeutic solutions for preventing the spread of this infectious agent.
TB is considered one of the most dangerous infectious diseases in the world, still causing over one million deaths each year. In humans, the disease is caused by a bacterium known as "Koch's bacillus" which spreads efficiently through aerosol. TB also affects a wide range of other mammals, but, despite having a genetic heritage very similar to that of the human strains, the animal strains of tuberculosis bacilli are very rarely involved in human-to-human transmission chains. By comparing the genomes of multiple strains, the scientists identified three mutations that were present in all of the animal strains but not in human strains. In experiments where these mutations were transferred to human tuberculosis bacilli, the virulence of these bacilli was significantly reduced in various cellular and animal models. This work explains why tubercle bacilli of animal origin have little impact on the epidemiology of the disease in human populations.
