title: Humoral immune response of dogs after vaccination against leptospirosis measured by an IgM- and IgG-specific ELISA.
abstract: An IgM- and IgG-specific ELISA was used to measure the antibody response stimulated in dogs by vaccination with a leptospiral bacterin containing chemically inactivated Leptospira interrogans serotype icterohaemorrhagiae and serotype canicola leptospires. All dogs produced anti-leptospiral IgM and IgG. The IgM production was of the primary response type after each vaccination (primary vaccination, booster vaccination and annual revaccination). A substantial anti-leptospiral IgG response could be demonstrated only after the first booster vaccination and the annual revaccination. Annual revaccination resulted in a higher and much longer persisting IgG response than did the first booster vaccination. A revision of the vaccination scheme is suggested.
