Adsorption of phages SOCP and Dp-1 on S. pneumoniae strains. Rates of adsorption of SOCP and Dp-1 on S. pneumoniae R6 WT (black), R6-SOCP^R (light grey) or R6-DP1^R (dark grey). No adsorption occurred in the absence of bacteria (empty bar). Adsorption of SOCP on R6-DP1^R and adsorption of Dp-1 on R6-SOCP^R was not measured since no bacteriophage cross-resistance occurred in the mutants (see Table 1). ^***denotes significant differences in adsorption compared to the mock control (p < 0.0001; one-way non-parametric ANOVA). ^###denotes significant differences in adsorption compared to R6 WT (p < 0.0001; one-way non-parametric ANOVA)
