Gnotobiotic mice died 2 days after inoculation of a cytotoxigenic Clostridium difficile strain. Protection occurred when mice were previously inoculated with a strain of Escherichia coli or Bifidobacterium bifidum. Intestinal cytotoxin production was highly reduced in the surviving mice, whereas the C. difficile population level did not decrease to a great extent.
无菌小鼠在接种产细胞毒素的艰难梭菌菌株后2天死亡。若小鼠预先接种大肠杆菌或双歧双歧杆菌菌株,则可获得保护。存活小鼠的肠道细胞毒素产生大幅减少,而艰难梭菌的菌量水平并未大幅下降。
