Researchers developing probiotic yogurt-based drugs Researchers at Ben-Gurion University of the Negev (BGU) have for the first time identified new drug candidates based on molecules isolated from probiotic Kefir yogurt for combating pathogenic bacteria and treating various inflammatory conditions, including inflammatory bowel disease (IBD) and COVID-19 related cytokine storms. The research, published in Microbiome, a leading peer-reviewed publication was led by Orit Malka, a Ph.D. student of Prof. Raz Jelinek, GU vice president and dean for research and development. “These results are notable, since this is the first demonstration that virulence of human pathogenic bacteria can be mitigated by molecules secreted in probiotic milk products, such as yogurt or kefir,” said Prof. Jelinek. “Our research illuminates the mechanism by which milk fermented probiotics can protect against pathogenic infections and aid the immune system. Following promising results in animal models, we look forward to administering these drug candidates to patients who are experiencing a cytokine storm due to COVID-19 infection, or people suffering from acute inflammatory bowel pathologies, such as Crohn’s disease.”
