We report the full genome sequence of the non-pathogenic rabbit lagovirus Lagovirus europaeus/GI.3/O cun/FR/2006/06-11 (GI.3/06-11), collected from a healthy French domestic rabbit in 2006, and initially described as 06-11 strain. The sequence reveals a genomic organization similar to lagoviruses. It was 7,436 bases long and contained two open reading frames (ORF). A dipeptide variation at the potential p23/2C-like helicase cleavage site (EE instead of ED) was observed, a feature only shared with non-recombinant pathogenic lagoviruses in GI.2 and with two European brown hare syndrome viruses (EBHSV) collected in 1982 in Sweden. GI.3/06-11 has only one initiation codon at the beginning of the ORF2 like the avirulent Italian rabbit calicivirus (RCV) and EBHSV. Previous genetic analyses based on the capsid gene sequences showed that GI.3/06-11 was closer to the RCV and pathogenic lagoviruses GI.1 strains than other lagoviruses. This study, by revealing that GI.3/06-11 genome sequence significantly clustered with pathogenic GI.2 strains, gives prominence of new genetic relationship among lagoviruses and should contribute to understand the emergence of pathogenic strains.
