Purification and characterization from human parotid secretion of a peptide which inhibits hemagglutination of Bacteroides gingivalis 381.

abstract：:The Mfa1 protein of Porphyromonas gingivalis is the structural subunit of the short fimbriae and mediates coadhesion between P. gingivalis and Streptococcus gordonii. We utilized a promoter-lacZ reporter construct to examine the regulation of mfa1 expression in consortia with common oral plaque bacteria. Promoter acti...
