Anaplasma marginale infections were induced in 3 calves previously affected with neonatal immunohemolytic anemia (NIA). Similar infections were induced in 6 splenectomized and 7 intact calves. The response to infection by 3 calves (NIA recovered) closely resembled infections seen in splenectomized calves, being markedly more severe than similar infections in intact calves. Spleens from 3 (NIA recovered) calves after splenectomy were about one-tenth normal size. Marked recrudescing anaplasmal infections were not detected after splenectomy of the calves (NIA recovered), whereas marked recrudescing infections were observed after splenectomy of 2 intact calves having recovered from the primary infections.
对3头先前患有新生儿免疫溶血性贫血（NIA）的小牛诱发了边缘无形体感染。对6头脾切除的小牛和7头未切除脾脏的小牛诱发了类似感染。3头（已康复的NIA）小牛对感染的反应与脾切除小牛的感染情况极为相似，明显比未切除脾脏小牛的类似感染严重得多。脾切除后，3头（已康复的NIA）小牛的脾脏约为正常大小的十分之一。脾切除后，未在（已康复的NIA）小牛中检测到明显复发的无形体感染，而在2头从初次感染中康复的未切除脾脏小牛脾切除后观察到明显复发的感染。
