Complement contributes to control of <i>B</i>. <i>parapertussis</i>_<i>ov</i> strains.

<p>C57BL/6 mice (solid lines) or C3 deficient mice (dashed lines) were inoculated with <i>B</i>. <i>bronchiseptica</i> strain RB50 (A) or <i>B</i>. <i>parapertussis</i>_<i>ov</i> strain Bpp5 (B). Bacterial colonization was enumerated and Log₁₀ average of three to four mice per group +/- standard deviation was determined at the indicated time points. Dashed line indicates limit of detection. * indicates <i>p</i> value <0.05 between wild-type and C3 deficient groups.
