Caracterización de procesos infecciosos en poblaciones de jabalí del suroeste español

Résumé

Wild boar may act as a reservoir of important infectious agents, also pathogenic for humans and other species. Furthermore, these pathogens may affect the health status of wild boar populations. The aim of this thesis was to increase knowledge about wild boar's infectious diseases, assessing the clinical consequences caused by significant pathogens and studying the effects of several coinfections. In addition, the results allowed to propose several control measures to reduce the impact of these agents. Studies included in this thesis assess the impact of important pathogens like �Brucella suis� or the agents involved in the development of Porcine Respiratory Disease Complex in wild boar populations. In addition, the effects that coinfection with different pathogens (bacteria, viruses and parasites) have in the development of tuberculosis in wild boar are also studied. Finally, different outbreaks produced by typical porcine pathogens such as �Erysipelothrix rhusiopathiae�, �Pasteurella multocida�, �Streptococcus suis�, �Staphylococcus hyicus� and �Chlamydia suis�; or other less known agents like �Aeromonas hydrophila�, are also described. Results suggest that measures focused on reducing wild boar population density may help to reduce the prevalence of pathogens like �Brucella suis�. In addition, control measures focused on concomitant pathogens may be useful to control tuberculosis in wild boar.
