F. Ramare et al., INACTIVATION OF TRYPTIC ACTIVITY BY A HUMAN-DERIVED STRAIN OF BACTEROIDES DISTASONIS IN THE LARGE-INTESTINES OF GNOTOBIOTIC-RATS AND MICE, Applied and environmental microbiology, 62(4), 1996, pp. 1434-1436
Tryptic activity disappeared and trypsin was no longer detected with a
n antitrypsin antiserum in the large intestines of gnotobiotic rats an
d mice monoassociated with a human-derived strain of Bacteroides dista
sonis, whereas tryptic activity was not modified in the small intestin
es. This function was shown to be strain specific.
