[Development of an ELISA test to detect antibodies in vaccinated sheep or infected Corynebacterium pseudotuberculosis].

The aim of this study was to evaluate an indirect specific ELISA developed for the detection of humoral immune response in vaccinated sheep and/or challenged with a Corynebacterium pseudotuberculosis strain. Healthy 4 month-old lambs were distributed into 4 groups: Group 1 immunized (G1, n = 5), Group 2 vaccinated/inoculated (G2, n = 8), Group 3 inoculated (G3, n = 2) and Group 4 control (G4, n = 2). Groups G1 and G2 received two doses of an experimental bacterin.
