the ac of bordetella species differ in molecular weight and , despite sharing at least two common non-overlapping epitopes ( bb05 , bb07 ) , antigenic differences are likely : sera from piglets artificially infected with virulent b. bronchiseptica developed high elisa titers against ac from b. bronchiseptica but low titers against b. pertussis-derived antigen .
