Invasive properties of different Bordetella parapertussis isolates. Invasion of human tracheal epithelial (HTE) cells was performed with 12822, BPP1 (PRN‐positive), FR3728 (PRN‐negative), FR3717 (PRN‐negative), FR3743 (PRN‐negative), FR3772 (PRN‐negative), FR3286 (PRN‐positive) and FR0388 (PRN‐positive). Each isolate was added to one well in a 24‐well tissue culture plate containing at least 105 cells/mL, such that the bacterium/cell ratio was 100 : 1. The invasion of HTE cells was assayed as described in Materials and Methods. Invasion by each isolate is reported relative to that of the B. parapertussis reference strain Values are the means and standard deviations of at least three experiments.

Bacterial lung colonization observed in mice after intranasal challenge with Bordetella parapertussis isolates. The reference strain and the isolates BPP1 (pertactin (PRN)‐positive) and FR3728 (PRN‐negative) were used. Groups of 4‐week‐old Swiss mice (n = 4) were challenged with 50 μL of bacterial suspension containing 5 × 106 CFU of B. parapertussis. Bacterial lung colonization was measured at the indicated time points after challenge, and the results are expressed as the weighted mean CFU per lung (log10‐transformed). The plots show the geometric means for four mice per time point.
