The mean absorbance values obtained with the two antigens (N = 38) were ERC-2 = 2.359 and 85 = 2.189. The mean absorbance values when the sera were divided into the three treatment groups were as follows pre-treatment: Isolate ERC-2 had an absorbance value of 2.418;Isolate 85 had an absorbance value of 2.688, 30-day post treatment: ERC-2 had an absorbance value of 2.452;85 had an absorbance value of 2.303 and 60-day post treatment: ERC-2 had an absorbance value of 2.150;85 had an absorbance value of 2.073 with the mean absorbance values of all treatment groups were ERC-2: 2.229 and 85: 2.141. This study indicates the potential for further evaluations of the two lysate antigens with regard to antibody detection in dog sera with the ERC-2 reagent slightly more reactive than the 85 lysate antigen.展开更多
