Figure 1.

Number of porcine reproductive and respiratory syndrome virus (PRRSV) whole-genome sequencing (WGS)-positive cases per type of clinical sample. PRRSV WGS was attempted only on PRRSV reverse-transcription quantitative PCR (RT-qPCR)-positive cases. The “all samples” group includes all types of samples that we tested (i.e., lungs, sera, OF, PF, and PoT). The number in boxes is the % of PRRSV WGS successful cases. OF = oral fluid; PF = processing fluid (i.e., castration liquid); PoT = pool of tissues; WGS (+) = PRRSV WGS success; WGS (−) = PRRSV WGS failure.
