The family contain important human and mammalian pathogens that are vectored by different arthropod species. The ground supernatants of mosquitoes were used to inoculate in BHK-21 and C6/36 cells for virus isolation. Then, the viral complete genome sequence was obtained and used for phylogenetic analysis. In this study, we observed a cytopathic effect (CPE) in mosquito cells (C6/36) and rod-like virion after inoculating a pool of samples collected in Shanxi Province, China, in 2019 (SX1916). Meta-transcriptomics sequencing revealed the presence of two distinctive rhabdoviruses with similar abundance levels, namely, Shanxi rhabdovirus (SXARV) and Shanxi Arboretum virus (SXABTV). Despite the fact that the SXARV genome (9590 nt) was much shorter than that of SXABTV (11,480 nt), both belonged to the group within whose genomes encoded five proteins (N, P, M, G, and L) and a small hydrophobin (U1) and the difference in lengths is mainly caused by a substantially shorter N protein encoded by SXARV. On the phylogenetic tree, SXABTV was closely related (90.7% amino acid identity at L protein) with the Arboretum virus isolated from Psorophora albigenu mosquitoes in Peru in 2014, whereas SXARV was distantly related to Rio Chico virus (63.3% amino acid identity), a genetic distance large enough to be defined as a new species within . Collectively, we report a simultaneous isolation of two related rhabdoviruses from that marked the circulation of almendraviruses in Shanxi, China.
该病毒家族包含重要的人类和哺乳动物病原体,由不同的节肢动物物种作为传播媒介。用蚊子的地面上清液接种BHK - 21和C6/36细胞进行病毒分离。然后,获得病毒全基因组序列并用于系统发育分析。在本研究中,我们在接种2019年在中国山西省采集的一组样本(SX1916)后,在蚊子细胞(C6/36)中观察到细胞病变效应(CPE)和杆状病毒粒子。宏转录组测序揭示了存在两种丰度水平相似的独特弹状病毒,即山西弹状病毒(SXARV)和山西植物园病毒(SXABTV)。尽管SXARV基因组(9590 nt)比SXABTV基因组(11480 nt)短得多,但两者都属于基因组编码五种蛋白质(N、P、M、G和L)以及一种小疏水蛋白(U1)的病毒群,长度差异主要是由SXARV编码的N蛋白明显较短所致。在系统发育树上,SXABTV与2014年从秘鲁白纹按蚊中分离出的植物园病毒密切相关(L蛋白氨基酸同一性为90.7%),而SXARV与里约奇科病毒关系较远(氨基酸同一性为63.3%),这种遗传距离足以被定义为该病毒群内的一个新物种。总体而言,我们报告了从蚊子中同时分离出两种相关的弹状病毒,这标志着中国山西省存在阿尔门德拉病毒的传播。
