“…Greater discrimination within and between members of the major Leishmania complexes requires recombinant DNA selection of specific sequences (23). Specific recombinant probes for L. major (140,229,237), Leishmania tropica (185), Leishmania aethiopica (159), L. donovani (72,89,95,130,174), and L. braziliensis (215) species complexes have now been reported, and there are increasing numbers of recombinant probes which may be able to distinguish geographically isolated parasite strains (23,72,130,320). kDNA hybridization can also be employed for identification of Leishmania spp.…”
