Multiomics technologies for infectious disease research and the role of dietary iron in promoting pneumococcal diseases

Uptake of micronutrients such as iron in human bloodstream and mucosal surfaces is an essential requirement for microbes to cause diseases. Bacteria are often “battle” with their human host over maximizing use of iron for a variety of cellular processes linked to pathogenesis such as biofilm formation and toxin expression (). In a series of research reports, I used advanced multiomics technologies such as proteomics, non-coding and mRNA expression and genome arrays to establish the important role for iron in pneumococcal diseases. These were some of the first studies describing the use of high throughput technologies in microbiology research.
