Abstract:
Two methods of molecular characterization, using monoclonal antibodies and enzyme electrophoresis, were employed in the identification of 36 stocks of Leishmania isolated from human and canine cases of American visceral (AVL) and cutaneous (ACL) leishmaniases in the northern part of Ceará State, Brazil. Molecular homogeneous strains of Leishmania donovani (chagasi) isolated from both human and canine hosts were detected in 14 municipalities. Two more parasite species, L. braziliensis braziliensis and L. mexicana amazonensis, were also detected in the state. The implication of these results with respect to both the clinical and epidemiological data are discussed.
