Sixteen stocks, 15 isolated from patients with cutaneous (CL), mucocutaneous (MCL), or recurrent cutaneous leishmaniasis, plus one from a dog with CL in Salta and Corrientes Provinces, Argentina, were studied by multilocus enzyme electrophoresis. Thirteen of the stocks from humans were grouped in two zymodemes; nine termed as KMS 1, four as KMS 2, and assigned to . Two additional stocks from CL cases expressed a KMS 4 enzyme profile, corresponding to . Although the parasites from the dog were also assigned to , its zymodeme, KMS 3, was not expressed in any of the current human isolates. The characterization of from a dog was done for the first time in Argentina. The importance of the intraspecific polymorphism in the induction of clinical forms and in the host-reservoir concept is briefly discussed, based on the zymodeme data of isolates from humans and dogs. The presence of was confirmed in the country.
