Antibody responses to M. bovis antigens detected by MAPIA with sera from FIV+ and FIV−, mc26020-vaccinated cats. Antigens immobilized on each strip are indicated on the right. These include seven recombinant proteins of M. bovis (ESAT-6 [Rv3875], CFP-10 [Rv3874], MPB64 [Rv1980c], MPB59 [Rv1886c], MPB70 [Rv2875], MPB83 [Rv2873], and Acr1 [Rv3391]), two polyprotein fusions (CFP-10/ESAT-6 and Acr1/MPB83), and one native antigen (M. bovis culture filtrate T/91/1378). Numbers of weeks after vaccination are shown at the top. Cat identification is at the bottom. Bands on the strips indicate the presence of detectable antibodies to corresponding antigens.
