Table 1 PT, FHA and PRN production by strains Bp-WWC and Bp-WWD and Bp-WWE

From: Construction of Bordetella pertussis strains with enhanced production of genetically-inactivated Pertussis Toxin and Pertactin by unmarked allelic exchange

Strain PT (μg/mL) FHA (μg/mL) PRN (μg/mL)**
Tohama wt 2.2 ND* ND*
Bp-WWC 2.61 ± 0.16 17.75 ± 3.30 2.48 ± 0.10
Bp-WWD 3.77 ± 0.53 14.33 ± 0.50 2.31 ± 0.17
Bp-WWE 4.49 ± 0.83 17.08 ± 2.21 4.18 ± 1.02
  1. *ND = Not determined **The amount in cell extract
  2. The values were the mean of 3 independent experiments with standard deviation except the data for PT of Tohama WT was obtained from two independent experiments
