The idea behind Isala originated in Prof. Sarah Lebeer’s research group – a team of scientists who are fascinated by bacteria and their positive influence on our health. This multidisciplinary team includes microbiologists, bioinformaticians and bioengineers who often collaborate with doctors like gynaecologists and general practitioners as well. The team is driven by serious concerns about the widespread use of antibiotics and the lack of alternatives. The World Health Organization predicts that by 2050, more people will be dying of antibiotic-resistant microbes than of cancer if we don’t start using antibiotics more responsibly. Microbiome research can help us design alternative strategies for antibiotic use, but also many other approaches that could benefit women’s health. That’s why this team of scientists will be analysing the precious Isala samples with the utmost care.

Reine Audenaert is a PhD candidate conducting research into new insights around the vaginal microbiome by mimicking the vaginal environment and vaginal communities in the lab. This allows drugs and personal care products to be tested for their safety and their effect on the vaginal microbiome. She has also conducted research on the role of lactobacilli in food fermentations.
But these researchers depend on sufficient samples for their ambitious research design. They are therefore assisted by, among others, Prof. Charlotte De Backer of the MIOS UAntwerpen Research Group and her team, Studio Maria, the Provincial Institute for Hygiene (PIH), Sensoa vzw, and almost the entire UAntwerp communication team. They help motivate enough participants and communicate about the importance of vaginal health.
