Gut Bacteria Drive Auto-Brewery Syndrome, Largest Study Confirms

A large Nature Microbiology study links auto-brewery syndrome (ABS) to ethanol-producing gut bacteria rather than fungi, with Klebsiella pneumoniae and Escherichia coli more prevalent in ABS patients and higher ethanol production during flares; a stool transplant case showed remission for over a year, suggesting microbiome-directed therapies (diet, probiotics, or transplants) could treat ABS, though fungus involvement isn’t entirely ruled out.
