Disease-causing pathogen rewires gut metabolism to secure nutrients for growth: Study

The findings suggest that disease-associated microbes can actively drive intestinal inflammation by reshaping host metabolism, suggesting new therapeutic possibilities to prevent or disrupt diseases like infectious diarrhea and colorectal cancer.
