Table 2 S. mutans GS5 biofilm formation on preformed S. gordonii biofilms. Mixed biofilms were formed as described under Materials and Methods. Total cell numbers of S. mutans S. gordonii (x105) were determined following dilution of the biofilm cells to three different levels. Data are the mean ± standard deviation of duplicate platings from one of two reproducible experiments.
