摘要

The Rhabdoviridae is a diverse family of negative-sense single-stranded RNA viruses which infects mammals, birds, reptiles, fish, insects and plants. Herein, we reported the isolation and characterization of 6 novel viruses from diseased fish collected from China including SCRV-QY, SCRV-SS, SCRV-GM, CmRV-FS, MsRV-SS, OmbRV-JM. The typical clinical symptom of diseased fish was hemorrhaging. Efficient propagation of these isolates in a Chinese perch brain cell line was determined by means of observation of cytopathic effect, RT-PCR and electron microscopy. Sequence alignment and phylogenetic analysis of the complete G protein sequences revealed that these isolates were clustered into one monophyletic lineage belonging to the species Siniperca chuatsi rhabdovirus.
