Cutaneous leishmaniasis (CL) is an endemic disease and a public health problem in Hama governorate located in the central region of Syria. The aim of this study was to characterize Leishmania species isolated from human skin samples. A polymerase chain reaction, restriction fragment length polymorphism (PCR-RFLP) assay, was performed on skin lesion material samples from 32 patients with confirmed CL by direct microscopic examination in order to prove its usefulness and efficiency for identification of Leishmania species.

Methods: We utilized 290 serum samples from endemic areas (patients group) and other regions (control samples) in Syria during 2002-2005 and the serological testing was brought to the applied the serological tests at the Department of Animal Biology, Damascus University, Damascus, Syria.
Results: Anti-Leishmania antibody was detected in 250 (92.
Objective: To evaluate the performances of 3 serological assays (direct agglutination test [DAT], fast agglutination screening test [FAST], recombinant protein [rK39] dipstick) test for use in primary care, for the diagnosis visceral leishmaniasis (VL) in Syria.
Methods: We utilized 267 serum samples obtained during 2007 from patient groups confirmed and suspected VL, confirmed cutaneous leishmaniasis, toxoplasmosis from endemic areas in Syria and control samples, and applied the 3 serological tests in the Damascus University, Damascus and Health laboratories at the same time, on these samples.
Results: Our data show that the tests were very sensitive, where the DAT was the most specific followed by FAST, then rK39 dipstick.
