In recent years, bats have been found to harbour many viruses, raising several questions about their role as reservoirs and potential disseminators of zoonotic viruses. We investigated the presence of six virus families in bats in three regions of Central-Southern Italy. Astroviruses were identified in seven of 13 bat species. Sequence analysis revealed marked genetic heterogeneity among the astroviruses identified, with nucleotide identity ranging between 60.26% and 87.62%. Astrovirus diversity was not associated with the bat species, the geographic areas or the bat colony, suggesting the circulation of several astrovirus strains in Italian ecosystems. Genetic diversification and interspecies transmission appear common in bat astroviruses and could provide, potentially, the bases for transmission to humans and other mammals. Yet overemphasizing this risk might have detrimental consequences for bat conservation and preservation of the important ecosystem services bats provide.
近年来，蝙蝠被发现携带许多病毒，这引发了一些关于它们作为动物传染病病毒的储存宿主和潜在传播者的作用的问题。我们在意大利中南部的三个地区调查了蝙蝠中六种病毒科的存在情况。在 13 种蝙蝠物种中，有 7 种检测到星状病毒。序列分析显示，所鉴定的星状病毒之间存在明显的遗传异质性，核苷酸同一性在 60.26%至 87.62%之间。星状病毒的多样性与蝙蝠物种、地理区域或蝙蝠群无关，表明意大利生态系统中存在多种星状病毒株的循环。蝙蝠星状病毒的遗传多样化和种间传播似乎很常见，这可能为病毒传播给人类和其他哺乳动物提供了潜在的基础。然而，过分强调这种风险可能会对蝙蝠的保护和蝙蝠提供的重要生态系统服务产生不利影响。
