title: Recognition of Leptospira interrogans antigens by vaccinated or infected dogs.
abstract: Antigenic recognition of leptospiral antigens by vaccinated or infected dogs was studied by microagglutination test (MAT) and by western blots. In western blots, serovar specific antigens detected by MAT migrated in the 18-31 kDa zone. The 25-31 zone seemed to be linked to antigens indicating virulence of the strain. These antigens are LPS. The first antibodies made after infection are produced against LPS migrating in the 14 kDa zone. Many protein antigens are common in leptospires belonging to different serogroups. Virulent strains exhibited specific antigens in the 45 and 32-34 kDa zones.
