Twenty-six pronghorn antelope (Antilocapra americana) were collected in an area of eastern Montana where bovine anaplasmosis is enzootic. Their sera were examined for evidence of anaplasmosis by the complement-fixation test. Strong false positive reactions (3+ and 4+ reactors) occurred for 19 of the sera tested; 6 sera were anticomplementary. Inoculation of antelope blood into anaplasmosis, and anaplasma bodies were not found in stained blood smears of antelope or recipient calves.
在蒙大拿州东部一个牛无形体病呈地方流行的地区采集了26只叉角羚（美洲叉角羚）。通过补体结合试验检测它们的血清，以寻找无形体病的证据。在所检测的19份血清中出现了强烈的假阳性反应（3+和4+反应者）；6份血清有补体结合反应。将叉角羚血液接种到牛体内后，在叉角羚或受体小牛的染色血涂片上未发现无形体和无形体小体。
