The missions of platform Genotyping of Pathogens and Public Health (PF8) are (i) To provide scientific and technological support to microbiological surveillance laboratories and (ii) To perform research on the diversity and evolution of microbial pathogens. Innovative genomics-based methods are developed and applied at large scales for molecular identification, pathogen discovery, strain tracking and evolution of pathogenic agents. PF8 collaborates mainly with national surveillance laboratories such as National Reference Centers (NRC) or hospital labs, and can be quickly mobilized for genotyping of large strain collections in case of epidemics.
Platform PF8 deploys four main types of activities: (1) Sequencing and genotyping services, including high reactivity in case of bio-emergency; (2) Collaborative research projects in the field of genotyping and population genetics of pathogens; (3) Technology-oriented research; (4) Research in microbial population biology.
SERVICES AND BIO-EMERGENCY
Approx. 100,000 sequences and minisatellite (VNTR/MLVA) analyses were realized in 2010. PF8 is partner of numerous scientific teams and of > 20 NRC. In 2010, PF8 has been strongly mobilized for the genetic analysis of Chikungunya and Dengue in collaboration with the French National Reference Centers for Arboviruses.
COLLABORATIVE RESEARCH PROJECTS
Approximately twenty collaborative projects are currently running. Examples are sequence-based genotyping of antibiotic-resistant Escherichia coli and Staphylococcus epidermidis isolates, Listeria monocytogenes worldwide diversity, and analysis of emerging Dengue and Influenza viruses on several continents.
The platform performs R&D on innovative diagnostic and genotyping technologies, e.g. resequencing DNA arrays for detection of pathogens. Several projects for discovery of novel pathogenic agents, genome-wide characterization of pathogens, and population genomics of viruses and bacteria, have started since the acquisition in 2010 of our second-generation sequencer, Illuminas HiSEQ-2000.
We develop bioinformatics tools and data analysis methods and statistical expertise. Our web-accessible databases (www.pasteur.fr/mlst; www.pasteur.fr/mlva, beta-lactamase databases) allow global standardization of strain tracking.
POPULATION BIOLOGY RESEARCH
We conduct research into the species and strain-level biodiversity and evolution of the bacterial pathogens Salmonella, Listeria, Klebsiella and Acinetobacter.
