Cross-species transmission can often lead to deleterious effects in incidental hosts. Parvoviruses have a wide host range and primarily infect members of the order Carnivora. Here we describe juvenile common palm civet cats () that were brought to the Singapore zoo and fell ill while quarantined. The tissues of two individual civets that died tested PCR-positive for parvovirus infection. Phylogenetic analysis revealed this parvovirus strain falls in a basal position to a clade of CPV that have infected dogs in China and Uruguay, suggesting cross-species transmission from domestic to wild animals. Our analysis further identified these viruses as genotype CPV-2a that is enzootic in carnivores. The ubiquity of virus infection in multiple tissues suggests this virus is pathogenic to civet cats. Here we document the cross-species transmission from domestic dogs and cats to wild civet populations, highlighting the vulnerability of wildlife to infectious agents in companion animals.
跨物种传播通常会在偶然宿主中导致有害影响。细小病毒具有广泛的宿主范围,主要感染食肉目动物。在此,我们描述了被带到新加坡动物园并在隔离期间生病的幼年普通棕榈狸猫( )。两只死亡的狸猫组织经PCR检测细小病毒感染呈阳性。系统发育分析表明,这种细小病毒株在中国和乌拉圭感染犬类的犬细小病毒进化枝中处于基部位置,表明存在从家养动物到野生动物的跨物种传播。我们的分析进一步确定这些病毒为食肉动物中流行的CPV-2a基因型。病毒在多个组织中的普遍感染表明这种病毒对狸猫具有致病性。在此,我们记录了从家犬和家猫到家养狸猫种群的跨物种传播,突出了野生动物对伴侣动物中传染因子的易感性。
