As reported by Gina Kolata in The New York Times: Bacteroides fragilis and a strain of E. Coli could potentially be contributing to the growth of colorectal tumors, and thus the development of colon cancer in many individuals, according to a recent study. Researchers showed that these bacterium can infiltrate the colon’s mucosal membrane and have particularly dangerous effects on the DNA of surrounding colon cells. Preclinical investigations with mice strengthened these findings. This could improve pre-screening efforts and help to minimize or prevent cancerous development in individuals with high concentrations of these bacteria.
