Oligonucleotide primer and probe sets used for amplification of hly and iap gene-specific fragments by PCR and RT-PCR. The hly-specific primer-probe set was designed on the basis of data obtained from GenBank (accession numbers U25443, U25446, U25449, and U25452) and previously published information (1). The iap-specific primer set was also designed on the basis of data obtained from GenBank (accession numbers X52268, M80348, M80349, M80350, M80351, M80352, and M80353) and previous reports (3).
