Hanneke Borgdorff received her medical degree with honours in 2011 at the University of Leiden. Since 2012 she has been appointed as PhD student at AIGHD and the Academic Medical Center in Amsterdam under supervision of Professor Janneke van de Wijgert of the University of Liverpool. Their research focuses on the vaginal microbiome of African and Dutch women, and how vaginal microbiota are associated with sexually transmitted infections and the mucosal immune system. Hanneke Borgdorff uses bioinformatic and statistical techniques to analyse results from 16S rRNA genomics and human proteomics experiments, and incorporates the results into epidemiological analyses.
Thursday 24 March 2016, Hanneke successfully defended her PhD, called “The Vaginal Microbiome, associations with sexually transmitted infections and the mucosal immune response”.

Date of thesis defense: 24/03/2016A healthy vaginal microbiota is dominated by lactobacilli. Disturbance of the microbiological vaginal microbiota balance (“dysbiosis”) is associated with an increased risk of acquisition of sexually transmitted infections including HIV, and preterm birth in pregnant women. Since 2002, studies have used molecular methods to investigate the complex relationship between vaginal microbiota and vaginal health. This thesis first reviews the findings of these studies.

This study examined the presence of vaginal Lactobacillus proteins among sex workers in Rwanda. “We looked at the relative abundance of Lactobacillus proteins, comparing women with a Lactobacillus-dominated vaginal flora or microbiota to women with dysbiosis or disturbance of the vaginal flora or microbiota. Lactobacillus proteins may play important roles in maintaining a healthy Lactobacillus-dominated microbiota. Dysbiosis is associated with increased risk of acquiring sexually transmitted infections, including HIV. During dysbiosis, the number of lactobacilli in the vagina decreases and a diverse mix of other bacteria becomes established. However, why dysbiosis happens in the first place remains largely unclear and currently there are no interventions available to help establish and maintain a Lactobacillus-dominated microbiota. We identified seven Lactobacillus iners proteins. Two glycolysis proteins and a ferritin-like protein from Lactobacillus iners were significantly associated with dominance of Lactobacillus iners, independent of vaginal pH or the abundance of Lactobacillus iners. A similar trend was seen for Lactobacillus crispatus proteins, but the number of women with a Lactobacillus crispatus-containing microbiota was smaller. These proteins might have important roles in maintaining a healthy Lactobacillus-dominated microbiota. Further study is needed to elucidate their function and their ability to prevent vaginal dysbiosis”.
