FIG. 8.
(A) BatB binds preimmune sera from rabbit, guinea pig, mouse, and rat. Outer membrane fractions prepared from wild-type B. bronchiseptica strain RB50 and ΔbatB strain RBAT were probed with preimmune sera collected from naïve rabbit, guinea pig, mouse, or rat. (B) BatB binds to both Fc and Fab regions of preimmune mouse IgG. Outer membranes prepared from RB50 and RBAT were probed with commercially available HRP-conjugated Fc fragments or HRP-conjugated Fab fragments purified from preimmune mouse IgG.
