descriptionPRRSV strain identified (e.g. IngelvacMLV like Wild Type) in isolate by sequencing. The submitter's lab performs reverse transcriptase PCR on various specimens, including tissue, serum, oral fluid, and semen, to detect and isolate the ORF5 gene. PCR products are then used for sequencing and identifying the PRRSV strain.
