isoenzyme characterization of leishmania isolates from lebanon and syria.leishmania parasites were isolated from 22 lebanese and 5 syrian patients with active skin lesions for whom the diagnosis was confirmed by histopathological examination. the isolates were characterized by starch gel electrophoresis and analysis of 13 enzyme systems. eight old-world reference strains were used for comparison. one syrian isolate belonged to leishmania major, and four syrian and two lebanese to leishmania tropica. contrary to expectations, the majority of lebanese isolates were rel ...200011357993
gp63 gene polymorphism and population structure of leishmania donovani complex: influence of the host selection pressure?the gp63 encoding genes were characterized by pcr-rflp in 35 isolates representative of the leishmania donovani complex (l. infantum, l. donovani, l. archibaldi and l. chagasi), with special attention to mediterranean l. infantum from different geographical origins, and in separate groups from old world leishmania (l. major, l. tropica and l. aethiopica). the aim was to evaluate how the possible selective pressure by the host on these important surface proteins would influence structuring of our ...200111197761
