Table 1.
IDV-positive samples analyzed in this study. The source and collection date are reported. The farm of origin of each strain is identified by number and the lineage attribution is based on the HEF segment. The availability of the isolated virus is reported in the last column. The viruses belonging to a lineage different from D/OK are in the grey rows. * The partial HEF sequence is not included in the phylogenetic tree.
