Number of viral sequences detected in the pig faecal sample, according to virus family.

*sequence identity: Contigs were compared to known sequences of the indicated virus families and the respective contig with the lowest tBLASTx E score was used for calculation of deduced amino acid sequence identities.**unclassified: The highest identities of these sequences were found to virus sequences, which have not been assigned to a virus family according to the data available in the GenBank database.
