Phylogenetic tree based on E2 encoding sequences (1119 nt) generated by the genetic typing module of the classical swine fever database (CSF-DB). A neighbor-joining tree comprising a pre-defined set of reference sequences and ten additional sequences obtained from endemic CSF disease situations in wild boar in Balkan countries between 1998 and 2010 is shown. Individually added sequences are highlighted in boldface and indicated by red arrows. In the default configuration of the genetic typing module, bootstrap values are calculated for 100 iterations.
