Phylogenetic relationship between the RNA sequences of Seewis virus (SWSV) detected sequences in the study (80639, 83068, 84169), based on the partial L-segment sequence. The isolates obtained from Swedish shrews are marked in red. The tree was generated by MEGA6 [12] using the Maximum Likelihood method based on the Tamura-Nei model [13]. The values on the branches indicate bootstrap values. Initial tree(s) for the heuristic search were obtained by applying the Neighbor-Joining method to a matrix of pairwise distances estimated using the Maximum Composite Likelihood (MCL) approach. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 16 nucleotide sequences. Codon positions included were 1st + 2nd + 3rd + Noncoding. There was a total of 273 positions in the final dataset
