New qPCR test rapidly distinguishes Leishmania species causing cutaneous leishmaniasis

In the disease-burdened provinces of northeastern Iran, where two species of a skin-ravaging parasite have long confounded clinicians, researchers have devised a molecular test that reads the thermal fingerprint of Leishmania DNA to distinguish one species from another within a single day. The method — qPCR-HRM — closes a diagnostic gap that once forced physicians to treat patients on guesswork while cultures grew and sequencing results traveled slowly back from distant laboratories. Though the study is preliminary, it points toward a future in which the right treatment can follow the right di
