However, when plated on the ΔOmpC host, we only observed a borderline significant level of plaque size difference between the Stf + and Stf - phages (0.49 vs. 0.75 mm 2 ; F [1,8] = 4.45, p = 0.068; however, the non-parametric Wilcoxon/Kruskal-Wallis test showed a significant difference, z = -2.01, p = 0.034 for the one-way test).
