Parvovirus infects a wide variety of species. The rapid evolution, environmental resistance, high dose of viral shedding, and interspecies transmission have made some strains of parvovirus infection difficult to control within domestic animal populations. Some parvoviruses in companion animals, such as canine parvovirus (CPV) 1 and feline parvovirus, have demonstrated minimal evolution over time. In contrast, CPV 2 has shown wide adaptability with rapid evolution and frequent mutations. This article briefly discusses these three diseases, with emphasis on virus evolution and the challenges to protecting susceptible companion animal populations.
细小病毒可感染多种物种。其快速进化、环境抵抗力、高病毒载量排毒以及种间传播，使得一些细小病毒株在家畜群体中难以控制。伴侣动物中的一些细小病毒，如犬细小病毒1型（CPV-1）和猫细小病毒，随着时间推移进化极小。相比之下，CPV-2表现出广泛的适应性，进化迅速且频繁发生突变。本文简要讨论这三种疾病，重点是病毒进化以及保护易感伴侣动物群体所面临的挑战。
