疱疹病毒几乎感染动物界每一种动物,这些病毒具有特殊的形态学,含有巨大的双链DNA,在核内复制DNA并通过细胞核内膜发芽成熟。多数疱疹病毒具有持续感染和致瘤特性。例如HSV—2病毒可能与人类宫颈癌、EB病毒与鼻咽癌有关。疱疹病毒由衣壳、内膜和囊膜围绕的中心髓核组成,髓核是病毒体最里面的结构,是由盘绕着蛋白棒的DNA组成。围绕髓核的衣壳外观直径在85—110nm之间,位于衣壳和囊膜之间的内膜看来就像一层无定形的物质,其量随病毒体及繁殖细胞型不同而改变。囊膜是一层包绕衣壳的坚固的鞘,山表层突起的三层膜组成。
The herpes virus infects almost every animal in the world of animals. These viruses have a special morphology that contains huge double-stranded DNA that replicates in the nucleus and sprouts through the endometrium. Most herpes viruses have persistent infection and tumorigenic properties. For example, HSV-2 virus may be related to human cervical cancer, Epstein-Barr virus and nasopharyngeal carcinoma. The herpes virus consists of the central nucleus surrounded by the capsid, the intima, and the capsule. The nucleus pulposus is the innermost structure of the virion and consists of DNA wrapped around a protein rod. The appearance of capsids around the nucleus pulposus is between 85 and 110 nm in diameter, and the intima between the capsid and capsid appears to be an amorphous material that varies with virion and reproductive cell types. Capsule is a layer of sheath surrounded by a solid sheath, the surface of the mountain three layers of membrane composition.
