Previously controlled bacterial infections can re-emerge due to antibiotic resistance or vaccine escape. Species of pathogenic bacteria comprise a huge amount of genotypic and phenotypic diversity. Our lab is interested in the diversity, evolution and epidemiology of bacterial pathogens and in the links between the genotypic and phenotypic (ecology, colonization, transmission, virulence, antibiotic resistance, immune response) diversity of the strains within particular species. We focus on three pathogens of high public health importance: Klebsiella pneumoniae, which causes various types of infections including urinary tract, respiratory and blood infections; Bordetella pertussis, the agent of whooping cough; and Corynebacterium diphtheriae, the agent of diphtheria. We combine epidemiological surveillance, microbiology, genomics, proteomics, bioinformatics and immunological approaches as well as in-vivo and in-vitro models of infection. We also develop and maintain genomic libraries of bacterial genotypes and strain nomenclatures that facilitate global collaborative surveillance and population biology of bacterial pathogens.

MedVetKlebs: Klebsiella pneumoniae from ecology to source attribution and transmission control
Klebsiella pneumoniae (hereafter, K. pneumoniae) is a major cause of hospital-acquired infections such as urinary infections, pneumonia, bloodstream infections, infections in newborns and in intensive-care unit patients. Some hypervirulent strains also cause community infections […]
SPARK: Transmission of multidrug resistant Klebsiella clones and genes – a One Health approach
The SPARK (Spread of Population-wide Antibiotic Resistance in Klebsiella) project, funded by the JPIAMR instrument of the European Union H2020 programme, seeks to address the complex issue of transmission of antimicrobial resistance genes and […]
Bordetella and whooping cough: Population Biology and Vaccination
Our research on Bordetella covers the population biology and epidemiology of various Bordetella species, including B. pertussis, the major agent of whooping cough; vaccine improvements; and the impact of vaccination on population evolution. Current […]
Diphtheria and Corynebacteria: genomics, evolution and epidemiology
Our research on Corynebacterium diphtheriae and related bacterial pathogenic species, including Corynebacterium ulcerans, aims at defining the diversity, evolution and epidemiology of the agents of diphtheria and related infections. We study human and animal clinical isolates […]
A descriptive analysis of pertussis in 4 different regions of the world Coordinated by Fabien Taieb, physician affiliated with the Center for Translational Science at the Institut Pasteur, responsible for the coordination of the […]
Population biology of the bacterial pathogen Klebsiella pneumoniae
Klebsiella pneumoniae is one of the most urgent threats to public health given its increasing resistance to antimicrobial agents including carbapenems, considered as last-resort antibiotics. In this project we aim to understand the ecological, epidemiological and […]
Genomic taxonomy of bacterial strains: universal nomenclatures for epidemiology and population biology
High-throughput sequencing has revolutionized our abilities to track and characterize novel bacterial strains as they emerge and disseminate globally. Genome-based epidemiological typing systems provide ultimate resolution for strain discrimination. Genome sequences may also be […]
Bioinformatics of genome sequencing applied to epidemiological surveillance of infectious agents
The Institut Pasteur has voluminous activities of microbial strain characterisation, in the context of epidemiological surveillance, biological resource centres collections management, and research. These activities involve National Reference Centers, WHO-collaborative centers, biological resources centers […]
LabEx IBEID – Integrative Biology of Emerging Infectious Diseases
