The immunoglobulin response of swine following experimental infection with Leptospira interrogans serovar pomona.
The antibody response of pigs following experimental infection with Leptospira interrogans serovar pomona was examined using enzyme immunoassay (EIA) and the microscopic agglutination test (MAT). Leptospires elicited the production of both IgM and IgG classes of antibody, with IgG levels persisting for much longer than IgM. A comparison of MAT and EIA indicated that the detection of specific IgM by EIA was potentially useful in distinguishing between past and recent infection in pigs. Agglutinins were also detected in the urine of infected animals but these antibodies could not be detected by EIA.
