FIG 1.

No difference in SDS susceptibility between WT and Δp66 B. burgdorferi. WT or Δp66 cells at 2 × 10⁶ cells ml⁻¹ in 5 ml BSKII supplemented with SDS at final concentrations of 0.0%, 0.1%, and 0.3% were incubated at 33°C up to 24 h. B. burgdorferi survival was quantified through plating for CFU. Percent survival was calculated by comparing each SDS condition to 0.0% SDS at each time point for each B. burgdorferi strain. Data are representative of two independent experiments. Error bars represent SEM. In some cases, the error bar is smaller than the symbols.
