The epidemiology ofSalmonella dublininfection in a dairy herd: II. Serology

Abstract
SUMMARY: A number of serological tests were evaluated in a study ofSalmonella dublininfection in a dairy herd. None of the tests used detected either of the two carrier animals from whichSalmonella dublinwas isolated at slaughter 7 and 17 months after the herd infection. The complement fixation tests used proved to be a better guide to the presence of recent herd infection than the conventional ‘0’ or ‘H’ agglutination tests.
