From: Necrotrophic growth of periodontopathogens is a novel virulence factor in oral biofilms
Expression of virulence genes from P. intermedia and P. gingivalis in presence of dead oral bacteria. (A) Relative fold change of virulence genes from P. intermedia after exposure to dead P. gingivalis. (B) Relative fold change of virulence genes from P. gingivalis after exposure to dead P. intermedia. *Designates a statistically significant up-regulation of virulence genes respect to house-keeping genes (p < 0.05).
