? 2022 Elsevier LtdOstreid herpesvirus 1 (OsHV-1) infection caused mortalities with relevant economic losses in bivalve aquaculture industry worldwide. Initially described as an oyster pathogen, OsHV-1 can infect other bivalve species, like the blood clam Scapharca broughtonii. However, at present, little is known about the molecular interactions during OsHV-1 infection in the blood clam. We produced paired miRNA and total RNA-seq data to investigate the blood clam transcriptional changes from 0 to 72 h after experimental infection with OsHV-1. High-throughput miRNA sequencing of 24 libraries revealed 580 conserved and 270 new blood clam miRNAs, whereas no genuine miRNA was identified for OsHV-1. Total 88–203 differently expressed miRNAs were identified per time point, mostly up-regulated and mainly targeting metabolic pathways. Most of the blood clam mRNAs, in contrast, were down-regulated up to 60 h post-injection, with the trend analysis revealing the activation of immune genes only when comparing the early and latest stage of infection. Taken together, paired short and long RNA data suggested a miRNA-mediated down-regulation of host metabolic and energetic processes as a possible antiviral strategy during early infection stages, whereas antiviral pathways appeared upregulated only at late infection.
