Plain-English summary
A dog from Rio de Janeiro was found to have skin lesions and was diagnosed with a mixed infection of two types of Leishmania parasites. Tests showed that one type was causing the skin issues, while the other was present in the dog's blood and lymph nodes. This case highlights the need for careful monitoring and identification of Leishmania infections in dogs, especially in areas where the disease is common. Treatment options for Leishmania infections can vary, so it's important for pet owners to discuss the best approach with their veterinarian.

Abstract
We report here the first case of co-infection with Leishmania (Viannia) braziliensis and Leishmania (Leishmania) chagasi in a naturally infected dog from Rio de Janeiro, Brazil. Isoenzyme characterisation identified the parasites isolated in culture from the cutaneous lesion as L. (V.) braziliensis and the isolates from blood and lymph node as L. (L.) chagasi. PCR analysis using specific primers followed by molecular hybridisation for direct Leishmania species identification in tissue fragments confirmed the presence of L. (V.) braziliensis DNA in the cutaneous lesion and of L. (L.) chagasi DNA in spleen and popliteal lymph node fragments. This report emphasises the importance of identification of Leishmania species infecting seropositive dogs in endemic areas, and the consequent re-assessment of control and epidemiological surveillance measures for the control of leishmaniasis, as is the case in Brazil.
