has role in taxon Neospora caninum tachyzoite protective antigen role protective antigen Neospora caninum protein NcDG1 Separate groups of gerbils were immunized with purified recombinant proteins singly or in combinations and animals were then challenged with N. caninum. The protective efficacy of each vaccination was determined by assessing animal survival rate. The highest protection efficacy was observed for combined vaccination with NcSRS2 and NcDG1 (67.5% survival) compared to control (17.4% survival). Vaccination with NcDG1 alone elicited 62.5% survival in the challenge model [PubMed: 15793355]. Allen Xiang Protegen ID: 618; NCBI Protein GI: 2149142; NCBITaxon: 29176 protein Oliver He
