Ten strains of oral streptococci, comprising nine species, were screened for their in vitro cohesive interactions with a freshly isolated strain of Neisseria pharyngis. Strains of mutans streptococci, Streptococcus salivarius, Streptococcus sanguis I, Streptococcus milleri and Streptococcus mitis were able to cohere with N. pharyngis cells attached to a salivary pellicle adsorbed to glass. The cohesion was either due to coaggregation between the different genera or modification of the salivary pellicle by N. pharyngis MW2. S. sanguis II and Streptococcus oralis strains could not cohere with the N. pharyngis strain. Extracellular polysaccharide formed from sucrose was found to mediate cohesion between certain strains of mutans streptococci or S. oralis and N. pharyngis MW2.
对包括9个菌种的10株口腔链球菌进行了筛选，以检测它们与一株新分离的咽奈瑟菌在体外的黏附相互作用。变形链球菌、唾液链球菌、血链球菌I、米勒链球菌和缓症链球菌能够与附着在吸附于玻璃上的唾液薄膜上的咽奈瑟菌细胞黏附。这种黏附要么是由于不同菌属之间的共聚作用，要么是咽奈瑟菌MW2对唾液薄膜的修饰作用。血链球菌II和口腔链球菌不能与咽奈瑟菌菌株黏附。发现由蔗糖形成的胞外多糖介导了某些变形链球菌或口腔链球菌菌株与咽奈瑟菌MW2之间的黏附。
