FIG. 1.
Preparative immunoblots of Mycobacterium bovis whole-cell sonicate antigen (A) or recombinant MPB83 (B) probed with sera from FIV− or FIV+ mc26020-vaccinated cats. Animal identification and FIV status are provided on the bottom margins, and molecular mass markers are provided in the left margin. Responses to ∼25-kDa, ∼32-kDa, and ∼35- to 37-kDa antigens are indicated by long, short, and heavy arrows, respectively (except with cat RGM5, which had a preexisting strong response to the 25-kDa antigen).
