The specificity and immunoglobulin classes reactive in the counter-immunoelectrophoresis (C.I.E.) method for the immuno-diagnosis of C. fetus infection in cattle.

Abstract

In heifers infected with one of two strains of Campylobacter fetus subsp. fetus (C842-148 and NCTC 5850), or C. fetus subsp. venerialis or C. jejuni, there was cross reaction in the counter-immunoelectrophoresis test between the strains of C. fetus but not between C. fetus and C. jejuni. IgG1 and IgA antibodies in the vaginal mucus were most reactive in the test.
