The trypanosomatid protozoa Leishmania is endemic in ~100 countries, with infections causing ~2 million new cases of leishmaniasis annually. Disease symptoms can include severe skin and mucosal ulcers, fever, anemia, splenomegaly, and death. Unfortunately, therapeutics approved to treat leishmaniasis are associated with potentially severe side effects, including death.

Traditionally, hamsters are experimentally inoculated in the snout or the footpad. However in these sites an ulcer not always occurs, measurement of lesion size is a hard procedure and animals show difficulty to eat, breathe and move because of the lesion. In order to optimize the hamster model for cutaneous leishmaniasis, young adult male and female golden hamsters (Mesocricetus auratus) were injected intradermally at the dorsal skin with 1 to 1.

Development of new therapeutic approaches for leishmaniasis treatment requires new high throughput screening methodologies for the antileishmanial activity of the new compounds both in vitro and in vivo. Reporter genes as the GFP have become one of the most promissory and widely used tools for drug screening in several models, since it offers live imaging, high sensibility, specificity and flexibility; additionally, the use of GFP as a reporter gene in screening assays eliminates all the drawbacks presented in conventional assays and also those technical problems found using other reporter genes. The utility of the GFP as a reporter gene in drug screening assays with Leishmania parasites depends on the homogeneity and stability of the GFP transfected strains.
