Mouse gut parasite making it easier for colitis
New research by scientists at the University of Toronto, Canada, shows that mice infected with Tritrichomonas muris protozoa are more likely to develop colitis – an inflammation of the colon. While investigating the causes of colitis in rodents, the research team noticed that their mice subjects were more susceptible to the disease if they had already been infected by the parasite. Further study showed that the presence of T. muris increased the amount of immune cells and the chemicals they produce in the animal’s gut, leaving the intestine lining more likely to be inflamed – giving colitis an increase chance of developing. This finding could help scientists to better understand similar interactions between hosts, like humans, and their parasites.
