      A toxin produced by bacteria found in dirty water kills off immune cells in the lining of the colon, meaning people whose guts are colonised by these bacteria are much more likely to develop a condition known as ulcerative colitis.

      „If MTB infections do play a role and are becoming more common, it might help explain why the incidence of IBD is rising.“

      Why would this be the case? I don’t think water hygiene is becoming any worse, so where would this bacteria be coming from that’s increased?

      Not an expert by any means but it’s waving flags for me that this line of research is backwards and rather, this bacteria is preferentially able to colonize people who have dysregulated immune function in their gut – which probably traces back to the usual suspects of diet, chemical pollution, and viral infections.

      Toxic bacteria is responsible for this? Dang, it’s always the suspect you least expect.
