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: the multidrug resistant 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.
