Evaluation of serological assays based on a novel excreted antigen preparation for the diagnosis of Cutaneous Leishmaniasis in Panama.

The objective of the present study was to determine the efficacy of prototype diagnostic serological assays for American Cutaneous Leishmaniasis (ACL) in Panama. As such, we prospectively sampled 100 cutaneous leishmaniasis case-patients and tested their sera in two serological assays based upon novel soluble antigen preparations made from propagating the parasites in a protein-free, serum free media. Using serum and a Leishmania mexicana antigen preparation to sensitize plates, the assay correctly identified 89% of the case-patients.
