The heterogeneity of various Porphyromonas gingivalis strains to adherence and invasive.

牙龈卟啉单胞菌与成人牙周炎有关。这种生物已经被证明附着在胶原蛋白上，胶原蛋白是牙龈组织的主要成分。此外，我们发现不同牙龈假单胞菌对胶原包被透明质酸的附着存在明显的异质性。无毒菌株粘附于口腔组织的程度高于毒力菌株粘附于龈沟的程度。我们还澄清了牙龈卟啉菌对十六烷的吸附与它们附着在羟基磷灰石表面形成的拼贴物上的数量之间的总体相关性。我们的研究证明了菌株疏水性的差异可能是由于不同的菌毛能够附着在胶原包被的透明质酸上。另一方面，囊泡具有粘附性，无论毒性如何，囊泡都粘附在膜或胶原包被的羟基磷灰石上。

Porphyromonas gingivalis has been associated with adult periodontitis in human. The organism has been shown to attach to collagen which is major component gingival tissue. Moreover, we found that there were clear heterogeneity among P. gingivalis strains in their attachment to collagen coated HA. Avirulence strains adherent to oral tissue much than virulence strains in gigival sulcus. We have also clarified that an overall corelation was noted between the adsorption of strains P. gingivalis to hexadecane and their numbers which attached to collage formed on hydroxyapatite surfaces. Our study has proved the evidence that the difference in hydrophobic properties of strains may be due to difference of fimbriae which has appeared to be capable of attachment to collagen coated HA. On the other hand, vesicles have the adhesion which were adherent to pellicle or collagen coated hydropxyapatite regardless of virulence.
