Bats play an essential role in maintaining ecosystems. Their unique characteristics increase the likelihood of interactions with various species, making them a potential source for the emergence and spread of infectious diseases. Hantaviruses are continuously expanding their range of hosts. This study presents the identification of a partial genome associated with Hantavirus in samples collected from neotropical bats. We conducted a metagenomic study using samples from Carollia perspicillata in Maranhão, Brazil. Tissue fragments were used for RNA extraction and subsequent sequencing. The resulting data was subjected to bioinformatic analysis. A sequence showing an identity of 72.86% with the L gene in the reference genome was obtained. The phylogenetic analysis revealed the study sequence, denoted as Buritiense, clustering within the Mobatvirus clade. The intragroup analysis showed a broader dispersion and were markedly asymmetric. This observation suggests the possibility that Buritiense could potentially represent a new species within the bat-borne hantaviruses, but further analyses are needed to provide additional insights if bats plays a role as reservoirs and the potential for transmission to human populations.
蝙蝠在维持生态系统中起着至关重要的作用。它们独特的特征增加了与各种物种相互作用的可能性,使它们成为传染病出现和传播的潜在来源。汉坦病毒不断扩大其宿主范围。本研究鉴定了从新热带蝙蝠采集的样本中与汉坦病毒相关的部分基因组。我们对来自巴西马拉尼昂州的 Carollia perspicillata 样本进行了宏基因组研究。使用组织片段进行 RNA 提取和随后的测序。对得到的数据进行生物信息学分析。获得了一个与参考基因组 L 基因具有 72.86%同一性的序列。系统发育分析显示,研究序列 Buritiense 聚类在 Mobatvirus 分支内。组内分析显示出更广泛的分散性和明显的不对称性。这一观察结果表明,Buritiense 可能代表了蝙蝠传播的汉坦病毒中的一个新种,但需要进一步分析,如果蝙蝠作为储主发挥作用以及向人类传播的潜力,以提供更多的见解。
