Fetal sera or thoracic fluids of the abnormal fetuses from different swine farms were tested for the presence of antibody to encephalomyocarditis (EMC) virus. Sera of swine fetuses infected experimentally with EMC virus were also tested. High antibody titers ranging 1:128-4096 were detected in both field and experimental samples. Detection of the positive antibody was associated with clinical herd history of increased mummification, stillbirth and neonatal death. The results suggest that EMC virus may be a natural cause of swine reproductive failure and fetal infection can be diagnosed by detecting specific EMC virus antibody in either fetal sera or thoracic fluids.
对来自不同猪场的异常胎儿的血清或胸液进行检测，以确定是否存在抗脑心肌炎（EMC）病毒抗体。还对经EMC病毒实验感染的猪胎儿血清进行了检测。在现场和实验样本中均检测到高抗体滴度，范围为1:128 - 4096。检测到阳性抗体与木乃伊化、死产和新生儿死亡增加的临床猪群病史相关。结果表明，EMC病毒可能是猪繁殖失败的自然原因，并且通过检测胎儿血清或胸液中的特异性EMC病毒抗体可以诊断胎儿感染。
