A probiotic yogurt-based drug can help in Covid

London – A new study, published in the journal Microbiome, led by researchers from the Ben-Gurion University of the Negev (BGU) in Israel, says the mechanism by which milk fermented probiotics can protect against pathogenic infections and aid the immune system. They are based on molecules isolated from Kefir yogurt, a fermented probiotic dairy drink made by infusing cow or goat milk with kefir grains containing yeast and lactic acid bacteria. It shows the kefir-secreted molecules can significantly reduce virulence of Vibrio cholerae — which causes cholera. The anti-bacterial effect was based on disrupting communication among the bacterial cells. Raz Jelinek, Professor at the BGU, said: “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. 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.”
