Efficiency of the Stool-PCR Test Targeting NADH Dehydrogenase (Nad) Subunits for Detection of Opisthorchis viverrini Eggs

Figure 2

The detection limits of OvNad subunits in various numbers of eggs in artificially spiked samples (M, 100 bp DNA marker; NC, no template control; PC, positive control from uncountable Ov-eggs dissected from adult O. viverrini; and 0, 1, 5, 10, 20, 50, and 100 are the number of Ov-eggs inoculated in stool specimens).
