Of 18 Hereford cattle imported into Quebec from the eastern U.S.A., five exhibited acute hemolytic anemia, icterus, depression, fever, anorexia and died; 11 were killed because they had positive or suspicious anaplasma titers and two were quarantined. Anaplasma marginale organisms were found in the erythrocytes of the sick animals by light and electron microscopy. The partial absence of erythrocytic plasmalemma on several electron photomicrographs suggested exit of the anaplasma bodies. Titers up to 1:320 in infected animals were found by the complement fixation test.
从美国东部进口到魁北克的18头赫里福德牛中，5头发病，表现为急性溶血性贫血、黄疸、抑郁、发热、厌食，最终死亡；11头因无浆体滴度呈阳性或可疑而被宰杀，2头被隔离。通过光学显微镜和电子显微镜在患病动物的红细胞中发现了边缘无浆体微生物。几张电子显微照片显示部分红细胞质膜缺失，提示无浆体逸出。通过补体结合试验发现感染动物的滴度高达1:320。
