概要

論文の詳細を見る
Neisseria sicca, N. mucosa and N. subflava were coaggregated with Streptococcus mutans, S. sobrinus, S. sanguis, S. gordonii, Actinomyces viscosus, A. naeslundii, or Fusobacterium nucleatum subsp. nucleatum. These coaggregations were not inhibited by amino acids, sugars, or EDTA, and suggesting that heat stable cell surface factors from the heat treatment of each kind of cell are involved in the coaggregation. Culture supernatant of N. sicca, N. mucosa, and N. subflava aggregated with S. sanguis, A. viscosus and A. naeslundii. These culture supernatants promoted coaggregation among the microorganisms which do not occur each other in the native cells. These results suggest that N. sicca, N. mucosa and N. subflava, early colonizers, are associated with dental plaque formation, followed by participation of secondary colonizers and the initial steps of cariogenic bacteria adherence.
