The Swine Disease Reporting System is introducing the SDRS PRRSV BLAST tool, a one-of-a-kind implementation of a Basic Local Alignment Search Tool specific to the PRRSV ORF5 sequences. The tool’s focus is to help answer spatiotemporal questions regarding query sequences and detect any new sequences entering the SDRS database.
The web-based tool allows veterinarians, producers and other users to compare their ORF5 sequences with those in the SDRS database, identify sequences present in the database by level of nucleotide identity, and view where the resulting sequences occurred before, when they occurred, what is the percentage similarity of these sequences with the query sequence as well as the lineage and RFLP of the sequences.
The web-based application (Figure 1) can be found on the SDRS website. The SDRS team can be contacted if additional information or help interpreting the tool’s results is required.
