Correlation between ELISA reactivity and MAP titre as determined by qPCR. Panel A; Correlation of faecal MAP titre as enumerated by qPCR vs ELISA (Paralisa™) reactivity of matched cervine blood samples (Johnin antigen); Spearman correlation r = 0.4325; p <0.0001. Panel B; Correlation of faecal MAP titre as enumerated by qPCR vs ELISA (Paralisa™) reactivity of matched blood samples (Protoplasmic antigen); Spearman correlation r = 0.4006; p < 0.0001. n = 663. Red circle = Overall Paralisa™ result = positive; Light green circle = Overall Paralisa™ result = negative.
