Leishmania and Malaria Research Unit

The research group was established in 1984. It is a center for diagnosis, treatment, research and training for health personnel who work with the Estrategia Sanitaria de Prevención y Control de Enfermedades Metaxénicas del HNCH and Molecular Epidemiology Laboratory of IMT, in order to perform multidisciplinary research studies on leishmaniasis. That allow us to a better understandment of this disease that affects mainly poor, rural population that generally receive little support from the Peruvian government. The purpose of this Unit is to provide solutions in both the treatment and prevention of this disease. The novelty of this research unit is that it enables integrated collaborative work with scientists from the clinical area, field research, as well as professionals from the basic sciences (molecular biology, genetics, immunology, etc.), including also the search for solutions on the UTA in the country.
