Susceptibility of EPS-I to complement-mediated killing. Cells (104 c.f.u.) of the wild-type strains CTG38 and CTG-R5, the CTG1291 and CTG1701 mutants that lack EPS-I, and the complemented mutant CTG1701-C were assayed for complement susceptibility. Data represent multiple experiments and the total number of samples assayed for each strain was 27 for CTG1701-C and 36 for all other strains. Means with the same number of asterisks were not significantly different from each other, but there were significant differences between means with a different number of asterisks. Error bars, sem.
