Microbiome Research

The major focus of this core programme is to understand how microbes can perturb  the vaginal microbiome environment from an optimal and healthy state to that of sub-optimal or dysbiotic state. Recently, there is increasing evidence of the role in microbial dysbiosis defined as a shift from a less diverse and Lactobacillus dominant vagina to that of a more diverse microbial environment that includes a dominance of non- Lactobacillus spp in fueling genital inflammation.- Importantly, through Dr Sinaye Ngcapu’s microbiome research programme, his group discovered stably colonized participants with Lactobacillus crispatus , and these isolates that were subsequently included in a clinical trial of a live biotherapeutic (LBP) product that was funded by the Bill and Melinda Gates Foundation.  This LBP trial is currently ongoing and results are anticipated in June 2025. Besides this major advancement, Dr Ngcapu’s group is also invested heavily into understanding the mechanisms behind persistent bacterial vaginosis and the drivers of metronidazole resistant BV.  In addition, this group intends on exploring various BV isolates through in vitro assays including the organ on chip, how a phage may be able to “rewire” the dysbiotic state of the vaginal microbial environment to that of a healthy and optimal state.
