To create the 70-nt InflA probes, nt 725-794 of the matrix protein 2 gene segment 7 of Influenza A H3N2, accession nr CY023083, was used as query in BLASTn (GenBank database at NCBI, NIH). The Norovirus probe sequence comprises nt 646-715 of the capsid gene of the Norwalk-like virus, accession nr AY274264. The probes for detection of rotavirus were made using sequence EU372725 of the Human rotavirus A strain CMH171/01 inner capsid protein (VP6) gene as query. The probe region chosen, nt 112-178, was analyzed using the haplotype function of ConSort ß . Two differently degenerated probes containing dInosines were designed from each of the two major haplotypes, which potentially covered all rotavirus group A variations recorded in GenBank.
