Enteric Bacterial Pathogens Unit
Institut Pasteur 25-28 rue du docteur Roux, 75015 Paris
Research area of the Unit
The “Unité des Bactéries Pathogènes Entériques » (BPE Unit) is a Unit with both Research and Public Health activities. It comprises the French National Reference Center (NRC) for Escherichia coli, Shigella and Salmonella, the NRC for Vibrio and Cholera, and the World Health Organization Collaborating Center for Reference and Research on Salmonella (WHO CC-Salm). The research of the BPE Unit focuses on the biodiversity of enteric bacterial pathogens (population structures of Salmonella, Shiga toxin-producing E. coli, Shigella, and Vibrio, dynamics of particular populations, including those resistant to antibiotics) and on development of new molecular typing or subtyping methods for Public Health purposes.
Contribution to the programme
The BPE Unit will contribute to the present programme by bringing its long-term expertise on enteric bacterial pathogens, such as Salmonella, Shigella, Shiga toxin-producing E. coli and Vibrio. In a context of emergence (foodborne, waterborne or human-to-human outbreaks; bacterial population resistant to antibiotics; bacterial populations with particular virulence traits), for a better characterization of the emerging strain, we will (i) perform molecular and genomic epidemiology, (ii) determine the antimicrobial resistance determinants and (iii) develop molecular tools for rapid identification of the strain of interest. Thanks to the large collection of the BPE Unit (>300,000 strains stored since the 1940s), spatio-temporal evolution of the emerging pathogen could be analyzed in order to get a better understanding of the bacterial key factors involved in this emergence.
