Table represents comparison of detectable RT-qPCR units per gram of oyster. aResults from analysis of oysters from TN. cOutbreak from imported oysters in WA. dOutbreak
from imported oysters in PA. VGenogroup determined by RT-qPCR, no genotyping was performed. bOutbreaks 5 and 7 yielded partial sequences therefore accurate genotyping
could not be determined. ∞Below limit for quantification or sequencing. *No clinical specimen was collected for testing. gExtraction efficiency using SMSV-17 or MNV as an
extraction control
