Bartonella infections were investigated in bats in the Amazon part of Peru. A total of 112 bats belonging to 19 species were surveyed. Bartonella bacteria were cultured from 24.1% of the bats (27/112). Infection rates ranged from 0% to 100% per bat species. Phylogenetic analyses of gltA of the Bartonella isolates revealed 21 genetic variants clustering into 13 divergent phylogroups. Some Bartonella strains were shared by bats of multiple species, and bats of some species were infected with multiple Bartonella strains, showing no evident specific Bartonella sp.-bat relationships. Rarely found in other bat species, the Bartonella strains of phylogroups I and III discovered from the common vampire bats (Desmodus rotundus) were more specific to the host bat species, suggesting some level of host specificity.
本研究调查了秘鲁亚马逊地区蝙蝠中的巴尔通体感染情况。共调查了 112 只蝙蝠，分属于 19 个物种。从 24.1%（27/112）的蝙蝠中培养出了巴尔通体细菌。感染率在每个蝙蝠物种之间从 0%到 100%不等。对巴尔通体分离株 gltA 的系统发育分析显示，有 21 种遗传变异聚类为 13 个不同的系统发育群。一些巴尔通体菌株存在于多个物种的蝙蝠之间，而一些蝙蝠物种则感染了多种巴尔通体菌株，表明没有明显的特定巴尔通体属-蝙蝠关系。在其他蝙蝠物种中很少发现的从普通吸血蝙蝠（Desmodus rotundus）中发现的 I 组和 III 组巴尔通体菌株与宿主蝙蝠物种更为特异，表明存在一定程度的宿主特异性。
