Electron microscopic examinations were made on negatively stained preparations of supernatant fluids from cell cultures infected with haemagglutinating encephalomyelitis virus (HEV). The studies revealed that all related strains of the virus so examined were morphologically similar to coronaviruses. One strain, of similar origin, but known to differ serologically from the others, was shown to resemble the paramyxoviruses.
对感染血凝性脑脊髓炎病毒(HEV)的细胞培养上清液的负染制剂进行了电子显微镜检查。研究表明,所有经检查的该病毒相关毒株在形态上与冠状病毒相似。一个来源相似但血清学上已知与其他毒株不同的毒株,显示出与副粘病毒相似。
