FIGURE 5.

Effect of PYO and Sb-1 phage preparations on viability of biofilm-embedded mono and mix bacteria populations. S. aureus/P. aeruginosa mono- (A,B) and dual-species (C) biofilms formed on porous glass beads were exposed to phages. Data are reported as log10 CFUs/mL mean ± standard deviation of at least three independent experiments. Percent of cell reduction of treated samples compared to untreated samples was calculated as: percent reduction = [(A–B)/A]×100, where A is the mean number of viable bacteria of the growth control and B is the mean number of viable bacteria after exposure to PYO or PYO+Sb-1.
