Figure 4From: On-farm colorimetric detection of Pasteurella multocida, Mannheimia haemolytica, and Histophilus somni in crude bovine nasal samplesReceiver operating characteristic (ROC) curves for each selected primer set. The graphs illustrate the true-positive rate (TPR) and false-positive rate (FPR) of the quantitative loop-mediated isothermal amplification (qLAMP) assay for each primer using the combinations of bovine respiratory disease (BRD) bacteria presented in Additional files 11 and 12. TPR was calculated as TP/(TP + FN) and FPR was calculated as FP/(FP + TN). TP, true positive; FN, false negative; FP, false positive; TN, true negative; PM, Pasteurella multocida; MH, Mannheimia haemolytica; HS, Histophilus somni.Back to article page
