Inactivation of tryptic activity by a human-derived strain of Bacteroides distasonis in the large intestines of gnotobiotic rats and mice.
Tryptic activity disappeared and trypsin was no longer detected with an antitrypsin antiserum in the large intestines of gnotobiotic rats and mice monoassociated with a human-derived strain of Bacteroides distasonis, whereas tryptic activity was not modified in the small intestines. This function was shown to be strain specific.
