Ljungan virus (LV) (family Picornaviridae, genus Parechovirus) is a suspected zoonotic pathogen with associations to human disease in Sweden. LV is a single-stranded RNA virus with a positive sense genome. There are five published Ljungan virus strains, three isolated from Sweden and two from America, and are classified into four genotypes. A further two strains described here were isolated from wild bank voles (Myodes glareolus) caught in Västmanlands county, Sweden in 1994. These strains were sequenced using next generation pyrosequencing technology on the GS454flx platform. Genetic and phylogenetic analysis of the obtained genomes confirms isolates LV340 and LV342 as two new putative members of genotype 2 along with LV145SL, with 92% and 99% nucleotide identities respectively. Only two codon sites throughout the entire genome were identified as undergoing positive selection, both situated within the VP3 structural region, in or near to major antigenic sites. Whilst these two strains do not constitute new genotypes they provide evidence, though weakly supported, which suggests the evolution of Ljungan viruses to be relatively slow, a characteristic unlike other picornaviruses. Additional genomic sequences are urgently required for Ljungan virus strains, particularly from different locations or hosts, to fully understand the evolutionary and epidemiological properties of this potentially zoonotic virus.
