Superparamagnetic Iron Oxide-Labeled Leishmania major Can Be Traced in Fibroblasts.

We can conclude that SPIONs are safe, inexpensive, easy to use, and accurate, and a fast method to label parasite in cells that the parasite can be latent, such as fibroblasts. These findings can open a new window in diagnosis, pathogenesis, and treatment of cutaneous leishmaniasis and can be added to the literature.
