RT-PCR methods have been applied to the detection and sequencing of the glycoprotein gene of putative spring viraemia of carp viruses (SVCV) and pike fry rhabdoviruses (PFRV), including isolates from tench, grass carp, roach, bream and false harlequin, sheatfish and orfe. Phylogenetic analysis of a 550 nucleotide (nt) region of the glycoprotein gene identified 4 groups, I to IV. Significantly, the majority of viruses previously identified as PFRV formed a distinct cluster (Genogroup IV) which shared <80% nucleotide identity with the PFRV reference strain (Genogroup III). The similarity between another PFRV-like virus isolated from grass carp and representatives of Genogroups III and IV was also <80%, indicating that this virus belonged to a third group (Genogroup II). All of the putative SVC viruses were assigned to a 4th group (Genogroup I), sharing <61% nucleotide identity with viruses in Genogroups II to IV.
