2. Figure 1
Accumulation of ethidium bromide by Streptococcus pneumoniae strain R6:cat (parent; squares) and R6:cat-2 (mutant; triangles). Each point is the mean of three individual experiments; error bars represent — standard deviation. Fluorescent emission at 600nm is proportional to accumulation of ethidium bromide.
