Paratuberculosis en España: Importancia de los reservorios silvestres

Abstract

[ES]: Esta tesis aborda el papel de los animales silvestres en relación con la paratuberculosis, en la península ibérica bajo la hipótesis de que debido a su alta densidad poblacional de ciervos, la paratuberculosis podría ser detectada en un elevado numero de ciervos ibéricos. Además, otras especies, como el jabalí, los conejos o los carnívoros, también podrían constituir indicadores de paratuberculosis. En concreto, se plantean los siguientes objetivos: 1. Actualizar todas las informaciones vigentes sobre paratuberculosis en fauna silvestre 2. Analizar especificidad y sensibilidad de los métodos de diagnóstico en la detención de MAP; 3. Ver si MAP sea un factor significativo en la dinámica de la población de algunas especies de la fauna silvestre española 4. Caracterizar la diferencia de expresión de genes relacionados con la inmunidad en ciervos y bóvidos infectados con M. bovis y Anaplasma marginale. La tesis se estructura en cinco capítulos. El primero de ellos es una revisión bibliográfica sobre la paratuberculosis en la fauna silvestre, que permite conocer el estado actual de conocimientos sobre su posible implicación en el mantenimiento de MAP, su efecto sobre sus poblaciones, y las consecuencias de paratuberculosis sobre la vigilancia sanitaria de otras micobacteriosis, particularmente la tuberculosis. Los siguientes tres capítulos describen el papel del conejo como posible reservorio local de paratuberculosis en la península ibérica; la ausencia de utilidad de los cánidos ibéricos (lobo y zorro) como posibles centinelas de la circulación de MAP; y el hecho de que, contrariamente a lo esperado, el ciervo no constituye un reservorio de paratuberculosis en el área de estudio. El quinto y último capítulo analiza la expresión de genes relacionados con la inmunidad en respuesta a la infección de rumiantes por patógenos de los géneros Anaplasma y Mycobacterium.

[EN]: This thesis attempts to evaluate the role of wildlife in relation to pararatuberculosis in the Iberian Peninsula under the assumption that the contact between wildlife and domestic ruminants is increasing due to the demographic and geographic expansion of some species and to changes in management systems. In particular, we established the following objetives: 1. To collect and review the information of the scientific literature about paratuberculosis in domestic animals and wildlife. 2. To optimize some paratuberculosis diagnostic methods for application in wildlife. 3. To study the putative role of wildlife as a reservoir for paratuberculosis. 4. To identify new molecular mechanisms important in the Mycobacterium avium paratuberculosis (MAP) - host interaction. The thesis is divided into five chapters. The first one is a review on paratuberculosis in wildlife, which identifies the current state of knowledge about their possible involvement in the maintenance of MAP, its effect on populations, and the impact of paratuberculosis on health surveillance for other mycobacterial infection, particularly tuberculosis. The next three chapters describe the role of rabbits as a possible local paratuberculosis reservoir in the iberian peninsula, the putative role of the iberian canids (wolf and fox) as sentinels for MAP circulation, and the fact that, contrary to our expectations, deer are not a reservoir of paratuberculosis in the study area. The fifth and final chapter analyzes the expression of genes related to immunity in response to infection of ruminants with pathogens of the genera Anaplasma and Mycobacterium.
