FIG. 1.

Final titers of all single-strain infections. Five single-strain infections were conducted for each strain to control for the effects of infection duration and MOI in mixed-strain infection treatments. Data are mean log₁₀ pfu/mL of four replicate infections. Error bars are 95% confidence intervals (CI) from the nested ANOVA model: Titer of χ = β₀ + β₁Strain + β₂Treatment + β₃Treatment[Strain] + ε. Treatment is the combined effects of total infection duration: 64 hours (black) and 72 hours (white), and MOI: 0.05 (circle), 5 (triangle), and 10 (square); e.g., a black circle indicates that infection time was 64 hours and the inoculation MOI was 0.05. Strain labels on the X-axis correspond to those in Table 1.
