Figure 1From: Monitoring the prevalence of viable and dead cariogenic bacteria in oral specimens and in vitro biofilms by qPCR combined with propidium monoazideEffects of PMA (A and C) and EMA (B and D) on S. mutans and S. sobrinus cell viability. A total of (A and B) 2.77 × 106 CFU of S. mutans and (C and D) 2.85 × 106 CFU of S. sobrinus were treated with 0, 2.5, 25, and 250 μM PMA and cross-linked. After PMA and EMA treatments, bacterial cells were plated on Mitis-Salivarius agar plates and counted. The mean and S.D. values of independent triplicate data are shown.Back to article page
