Abstract

The family Togaviridae is described; it contains four genera--Alphavirus, Flavivirus, Pestivirus and Rubivirus--and additional members. The main characteristics of the family are as follows: single-stranded, linear RNA, molecular weight about 4 X 10(6). Virions have isometric nucleocapsids surrounded by a lipoprotein envelope containing host cell lipid and virus-specified polypeptides including one or more glycopeptides. Virions yield infectious RNA. There are at least 80 members; all the alphaviruses and most flaviviruses are arboviruses in the biological sense.

摘要

披膜病毒科已被描述；它包含四个属——甲病毒属、黄病毒属、瘟病毒属和风疹病毒属——以及其他成员。该科的主要特征如下：单链线性RNA，分子量约为4×10⁶。病毒粒子具有等轴对称的核衣壳，被一层脂蛋白包膜所包围，该包膜含有宿主细胞脂质和病毒特异性多肽，包括一种或多种糖肽。病毒粒子产生传染性RNA。该科至少有80个成员；从生物学意义上讲，所有甲病毒和大多数黄病毒都是虫媒病毒。
