Genetic immunization was used to functionally test the genes of C. abortus as vaccines in a mouse challenge system. Glu-tRNA Gln Amidotransferase (CP #2, gatC) was found to be protective. Three of the clones (CP #1–3) elicited protection that was statistically higher than the unvaccinated control, which has high variance (Stemke-Hale et al., 2005).
