Abstract

Human blood-associated partitivirus (HuBPV) was first identified through metagenomic analysis of serum samples from two Peruvians, but its natural host remains unknown. Here, we report the detection of an HuBPV strain (HuBPV-Bm) in the phytopathogenic fungus Bipolaris maydis strain HN11 in Hubei Province, China. The dsRNA1 and dsRNA2 of HuBPV-Bm show more than 97.6% and 98.8% nucleotide sequence identity, respectively, to those from the metagenomically discovered HuBPV strain (HuBPV-M). Notably, HuBPV-Bm contains a third dsRNA segment that was not reported for HuBPV-M. All mycelia derived from individual asexual spores of HN11 tested positive for HuBPV-Bm, as did nine out of 293 B. maydis strains collected across Hubei.

分离的人血液相关的部分病毒自然感染植物病原真菌双北极星。

人类血液相关局部病毒（HuBPV）最初是通过对两名秘鲁人的血清样本进行宏基因组分析发现的，但其天然宿主仍不清楚。在这里，我们报道了在中国湖北省的植物病原真菌双北极星菌株HN11中检测到HuBPV菌株（HuBPV- bm）。HuBPV- bm的dsRNA1和dsRNA2与元基因组学发现的HuBPV株（HuBPV- m）的核苷酸序列同源性分别超过97.6%和98.8%。值得注意的是，HuBPV-Bm包含HuBPV-M未报道的第三个dsRNA片段。来自HN11单个无性孢子的所有菌丝体均检测出HuBPV-Bm阳性，湖北各地收集的293株maydis菌株中有9株检测出HuBPV-Bm阳性。

期刊介绍： Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
