Abstract
Los protozoos del género Leishmania son transmitidos al hombre mediante las picaduras infectivas de hembras de distintas especies de flebótomo (Diptera: Psychodidae), convirtiéndose en agentes causales de la leishmaniasis, cuyas manifestaciones clínicas dependen de diferentes factores asociados al parásito y al hospedador. Estas formas clínicas varían desde lesiones cutáneas localizadas hasta formas viscerales, las últimas pueden ser mortales sin tratamiento.En Europa Leishmania infantum es el principal agente causal de la leishmaniasis cutánea y visceral, y las hembras de distintas especies del género Phlebotomus son los vectores implicados en su transmisión, la cual depende de un ciclo zoonótico en el que el perro es considerado el principal reservorio. La incidencia regional de la leishmaniasis se estima en menos del 2% de la carga global de la leishmaniasis de acuerdo con la estimación reciente de la OMS. Sin embargo,se considera que hay una importante subnotificación debido a la ausencia de un sistema de vigilancia centralizado. Durante la última década varios estudios epidemiológicos han demostrado un incremento de la prevalencia de leishmaniasis en algunos países endémicos, así como la aparición de nuevos focos relacionados con la propagación de la enfermedad hacia el norte del continente europeo...
Leishmaniasis is a vector-borne disease caused by flagellated protozoans of the genus Leishmania, parasites are transmitted by the bite of infected phlebotomine sand flies species(Diptera: Psychodidae). Clinical manifestations depend on different factors associated with the parasite and the host, ranging from localized skin lesions to visceral forms, the latter being deadly without treatment. In Europe, Leishmania infantum is the primary causative agent of cutaneous and visceral leishmaniasis, and females of different species of the genus Phlebotomus are the vectors involved in its transmission, which depends on a zoonotic cycle in which the dog is considered the main reservoir. The regional incidence of leishmaniasis is estimated at less than 2% of the overall burden of leishmaniasis according to the WHO recent estimate. However, is underestimated due to the absence of a centralized surveillance system...
