The influence of the presence of saliva from different salivary glands on the adherence of Streptococcus gordonii strain HG 222 to saliva-coated polystyrene surfaces was tested. In the presence of undiluted parotid saliva or diluted whole, submandibular and sublingual saliva the adherence of HG 222 was enhanced by the formation of small aggregates on the attachment surface. In the presence of undiluted whole, submandibular and sublingual saliva large aggregates were formed and the adherence to saliva-coated polystyrene surfaces was inhibited. Adherence in the presence of whole saliva compared to adherence in buffer was decreased when lower densities of bacterial suspension were used, although in this case in the presence of whole saliva smaller bacterial aggregates were formed. In conclusion, these results suggest that the presence of saliva in solution may both enhance and decrease the adherence of S. gordonii HG 222 to saliva-coated polystyrene surfaces, partly depending on the size of bacterial aggregates that are formed in the presence of saliva.
测试了来自不同唾液腺的唾液对戈登链球菌HG 222菌株黏附于唾液包被的聚苯乙烯表面的影响。在未稀释的腮腺唾液或稀释的全唾液、下颌下腺唾液和舌下腺唾液存在的情况下，HG 222的黏附通过在附着表面形成小聚集体而增强。在未稀释的全唾液、下颌下腺唾液和舌下腺唾液存在的情况下，形成了大聚集体，并且对唾液包被的聚苯乙烯表面的黏附受到抑制。当使用较低密度的细菌悬液时，与在缓冲液中的黏附相比，在全唾液存在下的黏附降低，尽管在这种情况下，在全唾液存在下形成了较小的细菌聚集体。总之，这些结果表明，溶液中唾液的存在可能会增强和降低戈登链球菌HG 222对唾液包被的聚苯乙烯表面的黏附，部分取决于在唾液存在下形成的细菌聚集体的大小。
