使用電子顯微鏡判讀絲狀病毒是可以的,但要用顯微鏡觀察必須要先經過培養
而培養需要時間,因此電子顯微鏡檢查不能算『快速判定』

Marburg viruses and Ebola viruses have.been successfully visualized directly by electron microscopy of both heparinized bloocl and urine obtained during the febrile period as well as in tissue culture supernatant fluids. The combination of the size and shape of the virions is sufficiently characteristic to allow a morphologic diagnosis of filovirus.
以絲狀病毒獨特的外型,直接從blood, urine和培養上清液檢體 EM觀察即可判斷。只是要鑑定是ebola 或Marburg 需免疫電顯(IEM)。
