Abstrakt: 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.
