Actinobacillus actinomycetemcomitans strains y 4 and n 27 adhere to hydroxylapatite by distinctive mechanisms

, : Actinobacillus actinomycetemcomitans strains y 4 and n 27 adhere to hydroxylapatite by distinctive mechanisms. Infection & Immunity 47(3): 654-658

A. actinomycetemcomitans strains Y4 and N27 adsorb to spheroidal hydroxyapatite (SHA) in roughly the same numbers per milligram of substrate and with the same tenacity as 2 previously tested. Cytophaga sp. Although the 2 strains of A. actinomycetemcomitans exhibited similar affinities and number of binding sites for SHA, their response to enzyme treatment and heating were very different. The capacity of strain Y4 to attach to spheroidal hydroxyapatite was diminished by treatment with proteases and phospholipases and was unaffected by neuraminidase, while strain N27 was unaffected by proteases and phospholipases and lost its binding capabilities when treated with neuraminidase.
