The BNC was synthesized by G. xylinus strain. On the other hand, magnetization of the BNC was realized through in situ precipitation of Fe2+ and Fe3+ ferrous ions inside the BNC mesh.
Cutaneous Leishmaniasis in the Dorsal Skin of Hamsters: a Useful Model for the Screening of Antileishmanial Drugs Sara M. Robledo1, Lina M. Carrillo1,2, Alejandro Daza1, Adriana M.

Vélez1 1Program for the Study and Control of Tropical Diseases -PECET-School of Medicine, University of Antioquia, 2School of Agrarian Sciences, University of Antioquia Optimization of the experimental hamster model for cutaneous leishmaniasis by intradermal injection of Leishmania promastigotes at the dorsal skin. This approach is useful during inoculation, follow-up, characterization of lesions, application of treatments and obtaining of clinical samples. Locomotion, search for food and water, play and social activities are preserved.
