Despite the great diversity of bats (64 species) in the State of Acre, northwestern Brazil, there are no studies on occurrence and diversity of Bartonella spp. in bats in this region. The present study investigated the occurrence and molecular identity of Bartonella spp. in spleen samples (n = 271) from bats of 30 different species from this region, within the Amazon biome. Twenty-one out of 208 (10.1%) samples positive in the PCR for the mammalian gapdh endogenous genes were positive in the qPCR for Bartonella spp. based on the nuoG gene. The two gltA Bartonella genotypes detected grouped with those previously identified in bats from other locations, expanding the diversity of genotypes associated with bats. This study provided the first molecular evidence of the presence of Bartonella spp. in bats in the state of Acre and in bats of the species Lophostoma silvicolum, Vampyressa thyone, Tonatia saurophila and Phyllostomus elongatus.
尽管巴西西北部阿克里州有 64 种蝙蝠（bat），但在该地区的蝙蝠中，关于巴尔通体（Bartonella spp.）的发生和多样性尚无研究。本研究调查了在亚马逊生物群落中，来自该地区 30 种不同蝙蝠的 271 个脾脏样本中巴尔通体（Bartonella spp.）的发生和分子特征。在对哺乳动物 gapdh 内源性基因进行 PCR 检测呈阳性的 208 个样本中，有 21 个样本在基于 nuoG 基因的 qPCR 中对巴尔通体（Bartonella spp.）呈阳性。检测到的两种 gltA 巴尔通体基因型与先前在来自其他地区的蝙蝠中鉴定出的基因型相同，扩大了与蝙蝠相关的基因型多样性。本研究首次提供了巴尔通体（Bartonella spp.）存在于阿克里州蝙蝠和 Lophostoma silvicolum、Vampyressa thyone、Tonatia saurophila 和 Phyllostomus elongatus 等蝙蝠物种中的分子证据。
