Felix Dube is a medical microbiologist with broader research interests in the microbial dysbiosis associated with infectious diseases. The current focus is on Streptococcus pneumoniae (the ‘pneumococcus’), a bacterium that is a major bacterial cause of diseases including pneumonia and meningitis worldwide. By applying high-throughput genome sequencing techniques, this work provides further insights into the pneumococcal pathobiome, especially changes in pneumococcal sero-epidemiology, pathogenesis through statistical and computational approaches to unravel genotype-phenotype associations. This work is interfaced with an in-depth characterization of the nasopharyngeal resistome in children colonized by pneumococci. A recent but rapidly expanding component of our research group is around the evolution of the microbiome at different body sites in African children and the relationship between the microbiome and child health, with a specific focus on respiratory and skin infections and on antimicrobial resistance.
Key areas of expertise:
Microbiome of respiratory and skin infections, genotype-phenotype associations
