Anaplasma marginale isolated from Virginia ( VAM ), from North Texas ( NTAM ), from Florida (FAM), and Anaplasma ovis from Idaho were used in these trials. Complement-fixation antigens from each of the 4 isolates were used to compare complement-fixing antibody titers of 10 cattle infected with VAM , 17 with FAM, and 6 with NTAM . Strong cross-reactions occurred with all antigens and sera. The homologous system generally showed higher average antibody titers. The serum antibody titers occurring with the A. ovis antigen were significantly lower than those seen with A. marginale antigens. Serum antibody titer differences as measured by FAM and NTAM antigens on sera from VAM , NTAM and FAM failed to reach significance. Serum antibody titer comparisons using VAM antigen were significantly different from those occurring with FAM and NTAM in most instances.
这些试验使用了从弗吉尼亚州分离出的边缘无形体（VAM）、从北德克萨斯州分离出的边缘无形体（NTAM）、从佛罗里达州分离出的边缘无形体（FAM）以及从爱达荷州分离出的绵羊无形体。使用这4种分离株各自的补体结合抗原，比较了10头感染VAM的牛、17头感染FAM的牛和6头感染NTAM的牛的补体结合抗体效价。所有抗原与血清之间均发生了强烈的交叉反应。同源系统通常显示出较高的平均抗体效价。绵羊无形体抗原所产生的血清抗体效价明显低于边缘无形体抗原所产生的血清抗体效价。用FAM和NTAM抗原检测VAM、NTAM和FAM血清时，血清抗体效价差异未达到显著水平。在大多数情况下，使用VAM抗原进行的血清抗体效价比较与使用FAM和NTAM时的结果存在显著差异。
