A study conducted by the Murdoch Children’s Research Institute and Royal Children’s Hospital found that bacteria that thrives in freezing temperatures is present in almost half of Victoria’s cases of childhood chronic inflammatory bowel disease. According to the study, mycobacterium avium paratuberculosis lives in the digestive system of a large proportion of newly diagnosed cases of Crohn’s Disease.


However, this is just one of the potential factors affecting the increase in immune disorders identified by the researchers.


Another major factor, the study proposes, is the decrease in childhood infectious diseases. “Over the last century, these infectious diseases have declined and as they have, we’ve had a rise in these immune system disorders,” said Professor Anne-Louise Ponsonby, group leader of Environmental and Genetic Epidemiology Research. “So we think this has to do with the way the immune system is trained.”
