传染性软疣病毒(MCV) 是痘病毒科的一种病毒,会使人类患上传染性软疣。传染性软疣病毒与痘病毒科的其他病毒有着复杂的结构,包括表面的膜,核心,以及侧体。病毒可能以包涵体或出芽等形式在宿主细胞膜内部成熟,并在短时间内散发大量病毒。据测量,传染性软疣病毒的直径约为200纳米,长度约为320纳米,高度则在100纳米左右。[1]
临床表现可用于诊断传染性软疣;传染性软疣病毒不能进行常规培养,手术活检可进一步进行诊断。
传染性软疣病毒共有4种,分别是MCV-1型、MCV-2型、MCV-3型和MCV-4型。MCV-1型是人类感染最普遍的;MCV-2型常见于成人主要通过性传播。[2][3][4] PCR技术可帮助确定并区分引起病变的是哪一种类型的MCV。[5][6][7]
基因组
[编辑]基因组为不分段的单分子线性双链DNA,由180000–200000个核苷酸组成。不同核苷酸之间通过共价键连接两端边缘以及重复复杂的序列。其中有160个基因已被确定。[8]
动物病毒
[编辑]有一种动物病毒可以使马和驴患上与传染性软疣类似的疾病。[9][10][11] DNA研究表明,该病毒与MCV是密切相关的。[12]
