Welcome to our research on the dynamic world of the gut microbiota! The human gastrointestinal tract is home to a diverse community of microbes - bacteria, viruses and other microorganisms that play an important role in keeping us healthy and protecting us from harmful pathogens. However, influences such as antibiotics or inflammation can disrupt this delicate balance and lead to conditions such as a bloom of enterobacteria, where harmful bacteria gain the upper hand. Our research is looking at how these microbial changes affect our health, focusing on enteric pathogens such as Salmonella and E. coli. Using synthetic microbial communities and gnotobiotic mouse models, we are studying the interactions between bacteria, the immune system and pathogens to better understand how these changes occur. Ultimately, our goal is to find new ways to restore balance in the gut, prevent infections and tackle the growing challenge of antibiotic resistance
