观察双歧杆菌与肠上皮细胞系Lovo 细胞粘附后对肠致病性大肠杆菌(EPEC)及产毒性大肠杆菌(ETEC)粘附的竞争性抑制作用。发现双歧杆菌能完全抑制EPEC与ETEC的粘附,这种作用可能是由于双歧杆菌的占位性保护机制,在空间上阻止了病原菌与Lovo细胞的进一步接近
To observe the competitive inhibition of adhesion of enterobacterial enterobacteriaceae (EPEC) and toxigenic E.coli (ETEC) after adhesion of Bifidobacterium and Lovo cells. It was found that Bifidobacterium can completely inhibit the adhesion of EPEC and ETEC. This effect may be due to the occupational protection mechanism of Bifidobacteria, which spatially prevented the pathogen from further approaching Lovo cells
