Analytical sensitivity limit of detection (LoD) analysis for the FMDV SAT1, SAT3 and SAT2 topotype VII rRT-PCR assays. FMDV genomic RNA was extracted from duplicate 10-fold serial dilutions (100 – 10−7 or 10−9) of the FMDV cell culture isolates SAT1/KEN/4/1998 (A), SAT1/KEN/121/2009 (B), SAT2/ SAU/1/2000 (C), SAT2/SEN/27/2009 (D), SAT3/ZIM/4/1981 (E), and SAT3/SAR/1/2006 (F) and were tested using the homologous serotype SAT-specific rRT-PCR assay as well as the FMDV pan-serotype 3D rRT-PCR assay. Mean Cq values are plotted with standard deviations.
