| molecular karyotype characterization of leishmania panamensis, leishmania mexicana, and leishmania major-like parasites: agents of cutaneous leishmaniasis in ecuador. | molecular karyotypes of leishmania isolates from patients with cutaneous leishmaniasis in ecuador were analyzed by pulsed-field gel electrophoresis (pfge) and southern blot hybridization. the dna karyotypes of l. major-like parasites were similar between two human isolates from a lowland coastal and a highland andean region, but were apparently different from those of eleven world health organization reference strains including l. major. the smallest chromosome of 240 kilobases in l. major-like ... | 1993 | 8517490 |
