Effect of the prc deletion on the abilities of E. coli to resist serum killing. (A) Survival of WT-RS218 and Δprc-RS218 in 60% NMS or HI-NMS. (B) Survival of WT-RS218 and Δprc-RS218 in 60% NHS or HI-NHS. (C) Survival of Δprc-RS218 trans-complemented with pCL1920-prc or pCL1920 and of WT-RS218 containing pCL1920 in 60% NHS. (D) Survival of otherwise wild-type strain L346 and Δprc-RS218 coincubated in 60% NHS. For all results, the data are presented as the survival rates in the original inoculums. The data are representative of three independent experiments performed in triplicate and are shown as the means ± standard deviations.
