Prior AIEC colonization leads to heightened cellular and proinflammatory cytokine responses.
People who retain a particular bacterium in their gut after a bout of food poisoning may be at an increased risk of developing Crohn’s disease later in life, according to a new study led by researchers at McMaster University. Using a mouse model of Crohn’s disease, the researchers discovered that acute infectious gastroenteritis caused by common food-poisoning bacteria accelerates the growth of adherent-invasive E. coli (AIEC) – a bacterium that has been linked to the development of Crohn’s.
Even after the mice had eliminated the food-poisoning bacteria, researchers still observed increased levels of AIEC in the gut, which led to worsened symptoms over a long period of time...
