Outline of Final Research Achievements

Post-kala-azar dermal leishmaniasis (PKDL) is a complication of visceral leishmaniasis (VL). In order to eradicate VL, it is necessary to understand the onset mechanisms underlying development of PKDL as well as to improve diagnostic methods for PKDL. As a possible risk factor for PKDL, we investigated the correlation between the medicine used to treat VL and the onset risk rate of PKDL, but there was no correlation between them. We successfully developed Real-time PCR based diagnostic method for PKDL and revealed that miltefosine, an anti-leishmanial drug, reduced the number of parasites in the skin lesions. Moreover, we developed a system using dry-LAMP to detect Leishmania donovani and verified the practicability of the system in Bangladesh.
