Identified virulence factors of Bordetella: Serum resistance
(Bordetella resistance to killing)
Related genes: brkA;
Keywords: Serum resistance; Characteristics: The brk locus was also found in B. parapertussis and B. bronchiseptica but not B. avium.
Functions: Outer membrane protein that mediates adherence and resists complement.
