BrkA confers resistance to killing by complement in
Bordetella pertussis. Complement resistance in
Bordetella bronchiseptica was examined. Four B. bronchiseptica strains possessed the brkA gene;
however, only three expressed the protein. Only the strain lacking BrkA
was susceptible to complement. Introduction of the B. pertussis
brkA gene restored BrkA expression to this strain but did not
confer resistance. brkA was mutated in the strains that
naturally expressed BrkA, and loss of BrkA did not confer sensitivity
to complement. As a species, B. bronchiseptica is more
resistant to complement than B. pertussis, and BrkA does not mediate resistance.
