Healed Lesions of Human Cutaneous Leishmaniasis Caused By Do Not Shelter Persistent Residual Parasites.

In human cutaneous leishmaniasis (HCL) caused by () , the cutaneous lesions heal spontaneously and induce a Th1-type immunity that confers solid protection against reinfection. The same holds true for the experimental leishmaniasis induced by in C57BL/6 mice where residual parasites persist after spontaneous clinical cure and induce sustainable memory immune responses and resistance to reinfection. Whether residual parasites also persist in scars of cured HCL caused by is still unknown.
