【 摘 要 】

DNA hybridisation, using probes labelled with 32P, was used to type Leishmania samples isolated from patients living in endemic areas of Mato Grosso State (Brazil), and clinically diagnosed as having tegumentary leishmaniasis. kDNA cloned mini-circle probes specific for the Leishmania mexicana and Leishmania braziliensis complexes were used. The results showed that L. braziliensis is the predominant group infecting human patients in the state. Sixty-eight samples were typed, 64 samples (94.1%) belonging to the L. braziliensis complex and only four (5.9%) belonging to the L. mexicana complex. Accurate identification of the Leishmania permits better orientation of the medical follow-up, since clinical manifestations may vary depending on the complex to which the parasite belongs. The epidemiological information furnished by the identification of the Leishmania in given endemic area is also essential for the design of appropriate control measures
