| Summary: | Objective: the objective of the present work was the detection of Leishmania sp. in Rattus rattus tail base skin through polymerase chain reaction (PCR) techniques. Material and Method: We analyzed 45 Rattus rattus skin samples from the urban area of the city of Corrientes in Argentina. The Leishmania spp detection was performed by nested PCR technique. Results: Leishmania DNA was detected in 22 samples out of 45 processed (49%) in the first round of amplification, and in 14 samples (31%) in the second round (31%). Conclusions: These results contribute to increase the existing information in our region on the possible relationship between Leishmania and Rattus rattus, considering the high prevalence found in skin added to the total absence of lesions. Other aspects should be further studied to establish the role of these animals in the epidemiological chain of the disease in an urban area endemic to leishmaniasis in other animal species. Objetivo: detectar Leishmania sp. en piel de cola de Rattus rattus a través de técnicas de reacción en cadena de la polimerasa. Material y Método: Se analizaron 45 muestras de piel de Rattus rattus del área urbana de la ciudad de Corrientes, Argentina. La detección de Leishmania sp se realizó mediante técnicas de PCR anidada. Resultados: En la primera ronda de amplificación se detectó ADN de Leishmania en 22 muestras de 45 procesadas (49%) y en 14 muestras en la segunda ronda (31%). Conclusiones: Estos resultados contribuyen a aumentar la información existente en nuestra región sobre la posible relación entre Leishmania y Rattus rattus, teniendo en cuenta la alta prevalencia encontrada en piel sumado a la total ausencia de lesiones. Otros aspectos deberán seguir estudiándose para establecer el rol de estos animales en la cadena epidemiológica de la enfermedad en una zona urbana endémica a leishmaniasis en otras especies animales. |
