ROC curves showing the diagnostic accuracy of each recombinant protein analyzed individually (A) or in combination (B) when combining the 3 control groups N2, N3 and N4 as a single group. In A, proteins are sorted from left to right by decreasing AUC values. The combination of the first 3 antigens (B, dark brown) provides best accuracy. Sample groups: P1, seropositive dogs; N2, housed vaccinated dogs; N3, stray dogs; N4, dogs with other febrile syndromes.
