摘要
试验中用电镜观察了牛病毒性腹泻病毒ＯｒｅｇｏｎＣ２４Ｖ株在感染新生牛睾丸细胞中的形态发生，成熟的病毒颗粒是直径约为５０ｎｍ的球形颗粒，内含直径约为３０ｎｍ的核心。病毒在宿主细胞的胞质内复制，通过糙面内质网膜出芽成熟。病毒可以通过外排或在细胞死亡后含有病毒颗粒的空泡崩溃而释放到胞外。
he morpho8enesis of bovine viral diarrhca virus(BVDV)strain Oregon C24V in bovine testiscell culture was exam ined by electron micraseopy,Virions were roughly round and approx imately 50nm in diameter with a 30nm core,Virus replication took piace within cytoplasm of hcot cells. Budding of BVDV through membrane of medified rough endoplasmic reticulum was obeer ved.The virusmight be released by exocytosis or by disintegration of the vacuoles containing virus after cell death.
