摘　　要：巴尔通体是一群全球广泛分布的细菌,部分种类能引起多种人兽共患病,宿主包括食肉类、反刍类、啮齿类、灵长类以及海洋中鲸类等哺乳动物。近年来,世界各地陆续报道蝙蝠能够携带巴尔通体。为了解全球蝙蝠巴尔通体流行情况,本文系统检索汇总了自2005年以来世界各地对蝙蝠巴尔通体的研究,较为详细地描述了巴尔通体在蝙蝠这一大类群中的感染状况、宿主分布及遗传进化关系等信息。分析发现,在31个国家和地区的106种蝙蝠体内检测到巴尔通体,表明蝙蝠是巴尔通体重要的动物宿主。通过对蝙蝠巴尔通体柠檬酸合酶基因(citrate synthase gene,gltA)序列构建系统发育树,发现绝大多数蝙蝠巴尔通体与其他宿主来源的巴尔通体亲缘关系较远,构成蝙蝠巴尔通体独立的类群,初步揭示这一类巴尔通体具有宿主特异性特征,提示巴尔通体可能与宿主蝙蝠存在协同进化关系。Background&Aim:Bartonellae is a worldwide group of bacteria that causes a variety of zoonoses.Their hosts include carnivores,ruminants,rodents,and even mammals such as marine whales.Recently,it has been discovered that Bartonellae can infect bats,one of the important host animals for Bartonellae,worldwide.This review summarizes studies of bat-borne Bartonella worldwide since 2005 to illustrate the prevalence of Bartonellae in bats.Context&Conclusions:Bartonellae has been detected in 106 bat species in 31 countries and regions around the world,indicating that bats are major animal hosts.The feeding habit of bats does not affect whether they can carry Bartonellae,which has been found in bats with multiple feeding habits.The phylogenetic tree based on gltA sequences of bat-borne Bartonella displayed that most bat-borne Bartonella sequences are distant from other host-derived Bartonella and constituted a bat-origin Bartonella group.Bat-borne Bartonella,which has spread with bats worldwide,is host-specific to a certain extent.It is hinted that there is coevolution between Bartonellae and bat hosts.
