New research led by @karinaxavierlab.bsky.social at 🇵🇹 @gimmfoundation.bsky.social demonstrates that a harmless strain of 🦠 #Klebsiella – discovered by chance in 🧫 laboratory experiments – can eliminate #infections and reduce gut inflammation in mouse models of inflammatory bowel disease. #IBD

Do people in the same household share strains when they have the same species? How many cells transmit when a strain is shared? Can strain composition be dynamic when species composition is stable? We answer these and related questions for the facial skin microbiome in our latest paper. 🧵[1/10]
