Mechanisms for pigmentation of Porphyromonas gingivalis and growth inhibition by yogurt-derived lactobacillus delbrueckii.

Cornacchione, Louis.


  • Porphyromonas gingivalis is an important pathogen implicated in the development of periodontitis. Cellular pigmentation is an important virulence factor of the oral pathogen P. gingivalis. We utilized a transposon mutant library of P. gingivalis strain ATCC 33277 and screened for pigmentation-defective colonies using massively parallel sequencing of the transposon junction (Tn-seq) to identify ... read more
