Pertactin is an outer membrane protein expressed by
Bordetella pertussis, Bordetella parapertussis,
and Bordetella bronchiseptica that induces protective
immunity to Bordetella infections. The immunodominant and
immunoprotective epitopes of pertactin include two repeated regions, I
and II. Comparison of these two repeated regions showed that B. parapertussis pertactin is invariant, whereas B. pertussis pertactin varies mostly in region I and B. bronchiseptica pertactin varies in both repeated regions I and
II, but mostly in region II. These differences may result from specific
characteristics of these Bordetella species.
