Viral families discovered in different sample types. The figure shows the viral families and the number of new viruses belonging to each family in (a) animal samples; “other”: families that have been described in less than eight reports; ND: viruses not belonging to known families; (b) environmental samples; “other”: families that have been described in a single report; ND: viruses not belonging to known families; (c) plant samples; “other”: families that have been described in a single report. For all sample types, “unclassified”: as defined in NCBI taxonomy and viral zone databases.
