Abstract
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.
摘要
在用源自人类的狄氏拟杆菌菌株单联的无菌大鼠和小鼠的大肠中，胰蛋白酶活性消失，且用抗胰蛋白酶抗血清不再检测到胰蛋白酶，而小肠中的胰蛋白酶活性未改变。该功能显示具有菌株特异性。
