RESUMEN
La leishmaniasis visceral (LV) es una enfermedad infecciosa de evolución crónica, causada por un protozoario, Leishmania infantum, que afecta al hombre y a los caninos; es transmitida principalmente por la picadura del vector Lutzomyia longipalpis, con incriminación de Lutzomyia evansi en partes de Colombia y Venezuela. El perro actúa como el principal reservorio doméstico del parásito en todo el mundo, haciendo parte del ciclo epidemiológico de transmisión humana. Dada la importancia epidemiológica de los caninos en el control de la LV y la necesidad de determinar el impacto real de la infección en las zonas endémicas, es fundamental el empleo de pruebas diagnósticas eficientes, que no subestimen la incidencia, ni la prevalencia de la enfermedad, y que permitan además obtener resultados confiables, que minimicen las reacciones falsas positivas y la reacción cruzada con otros parásitos relacionados. El presente artículo revisa las técnicas diagnósticas para la leishmaniasis visceral canina (LVC) y establece de forma general algunas prioridades de investigación y desarrollo en esta área.
ABSTRACT
Visceral leishmaniasis is an infectious disease of chronic evolution caused by the protozoan Leishmania infantum (Leishmania chagasi), which affects humans and canines. It is transmitted mainly by the vector Lutzomyia longipalpis, with incrimination of Lutzomyia evansi in parts of Colombia and Venezuela. Dogs are considered the main domestic reservoir of the parasite, constituting part of the epidemiological cycle of human transmission. Given the epidemiological importance of canines in the control of visceral Leishmaniasis and the need to determine the real impact of the infection in the endemic areas, the employment of diagnostic efficient tests is fundamental. These tests shouldn’t underestimate the incidence, or the prevalence of the disease; they should also allow the obtainment of reliable results that minimize the false-positive reactions and the cross-reactions with other related parasites. The present article revises the diagnostic methods for canine visceral leishmaniasis and establishes some research and development priorities in this topic.
