Design, Setting, and Patients After exposure to an index patient whose fatal illness was characterized by fever and hemorrhage at a primary care hospital and regional tertiary care hospital's isolation ward, secondary cases with febrile illness who were suspected of being exposed were tested for antibodies against Anaplasma phagocytophilum and by polymerase chain reaction and DNA sequencing for A phagocytophilum DNA.
HGA1990年在美国被创造，在欧洲被创造的时间则是在1997年。据报道，每年该疾病的感染人数在持续增加。有关数据显示，该种疾病在风行地区的感染率高达15%至36%，这意味着对该种疾病的诊断由于感染程度稍微或者是患者没有症状经常被遗漏。
It was suggested that anaplasma could be transmitted naturally by gadfly biting or contacting blood-contaminated fomites.
实验证明无浆体的感染方式有以下几种：腹腔、皮下接种、接触感染以及通过厩蝇等非蜱类吸血昆虫机械性传播。
Results indicated that the anaplasma could be observed by microscope in erythrocyte of experimental animals at 6th to 8th day, and the anaplasma reached peak number in erythrocyte at 16th to 20th day, disappearing at 25th day after infection.
结果表明，无浆体在小鼠和兔子体内呈现一定的规律性。无浆体在感染后第6d和第8d分别在小鼠和兔子血液中可以检测到；感染后第16d~19d和第17d~20d在两者体内达到感染高峰；感染后第20d和第25d均逐渐消失。
Artificial anaplasma infection model was established in experimental animals under immune suppression conditions by means of infection via contact, intra-abdominal and subcutaneous inoculation.
因此，可用小鼠或兔子在免疫抑制情况下建立无浆体人工感染动物模型。
The comparison of sequences showed that the determined sequence was most similar to those in GenBank (AF016546)(similarity level, 97.9%), Phylogenetic analysis indicated that the resulting sequence was more similar to those of Mycoplasma spp.(homo!ogy level, about 70%), but was farther from Anaplasma spp.(homology level, about 50%).
系统发育分析表明，所测序列与支原体属病原代表种的序列接近，同源性约为70%，而与无浆体科病原代表种的序列相差较远，同源性约为50%。
