Synthetic Peptides as Potential Antigens for Cutaneous Leishmaniosis Diagnosis

Table 3

Reactivity of peptides (P1, P2, and P3 and MIX) and soluble antigen (SA) against sera from patients with Chagas disease, leprosy, and tuberculosis. The cut-off was provided by the ROC curve.

Antigen	Cut-off	Chagas disease	Leprosy	Tuberculosis
P1	0.351	0/10	1/10	3/10
P2	0.327	1/10	2/10	1/10
P3	0.235	2/10	2/10	3/10
MIX	0.192	0/10	1/10	2/10
AS	0.101	6/10	2/10	0/10

MIX: P1 + P2 + P3; SA: soluble antigen of Leishmania braziliensis.
