Figure Lengend Snippet: The detection limit of the multiplex real-time PCR (mRT-PCR) assay. The detection limit of the assay was evaluated using 10-fold serially diluted plasmid DNA. Each serially diluted control DNA, ranging from 10 6 copies to 1 copy per reaction, was used to determine the detection limit of the RT-PCR assay. In the RT-PCR assay, the amplification curve of the specific probe for detecting SeV (A) , Mycoplama spp. (B) , R. pneumotropicus (C) , R. heylii (D) , Helicobacter spp. (E) , MNV (F) , MHV (G) , Salmonella spp. (H) , S. aureus (I) , S. moniliformis (J) , C. kutscheri (K) , and P. aeruginosa (L) is shown. The overall detection limit of this assay for each control DNA ranged from approximately 1 to 100 copy DNA per reaction. C T was plotted against the input of the quantity of each DNA (repeated 10 times). The linearity was generated by plotting the log quantity of each DNA versus the corresponding C T value, and the coefficient of determination of the linear regression was 0.993–1.0, with a slope ranging from −3.193 to −3.934. The fluorescence intensity is displayed on the Y -axis ( R 2 = reporter signal/passive reference signal). RFU, relative fluorescence unit; R 2 , fluorescence units.
