摘要
本实验提纯了绿脓杆菌粘液株的胞外粘液多糖物质（ＭＥＰ），并对其在细菌粘附中的作用进行了研究。结果发现纯化的ＭＥＰ制品或抗ＭＥＰ血清可以阻断绿脓杆菌粘液株对健康人的颊上皮细胞的粘附作用，证明ＭＥＰ确是绿脓杆菌粘液株的粘附素。
The mucoid exopolysaccharide (MEP) of Pseudomonas aeruginosa was purified from a mucoid strain. The role of the MEP in adherence of mucoid strain to the buccal epithelial cells (BEC) from healthy adults was studied. Our data showed that both the purified MEP and antiserum against the MEP could inhibit the adherence of mucoid strain of P. aeruginosa to BEC. It indicated that the MEP was the adhesin for mucoid strains.
