The successful replication of a viral agent in a host is a complex process that often leads to a species specificity of the virus and can make interspecies transmission difficult. Despite this difficulty, natural host switch seems to have been frequent among viruses of lower vertebrates, especially fish viruses, since there are several viruses known to be able to infect a wide range of species. In the present review we will focus on well documented reports of broad host range, variations in host specificity, and host shift events hypothesized for viruses within the genera Ranavirus, Novirhabdovirus, Betanodavirus, Isavirus, and some herpesvirus.
病毒在宿主中成功复制是一个复杂的过程，通常会导致病毒的物种特异性，使得种间传播变得困难。尽管存在这种困难，但低等脊椎动物（尤其是鱼类）的病毒似乎经常发生自然宿主转换，因为有几种已知能够感染广泛物种的病毒。在本综述中，我们将重点关注有关Ranavirus、Novirhabdovirus、Betanodavirus、Isavirus 属中的病毒的广泛宿主范围、宿主特异性变化以及假设的宿主转换事件的有充分记录的报告，以及一些疱疹病毒。
