Worldwide there is a need to develop strategies to control relevant infectious disease
agents, such as Mycobacterium bovis and Aujeszky’s disease virus (ADV) in wildlife
reservoirs. We describe observational data on the effects of Eurasian wild boar (Sus
scrofa) abundance reduction of approximately 50%, through increased culling on the
maintenance of two chronic infectious diseases: tuberculosis (TB) and Aujeszky’s
disease (AD) in a high prevalence region. Wild boar TB prevalence remained stable in the 10 control sites, whereas it decreased by 21-48% in the 3 treatment sites. In one treatment site, the annual wild boar abundance positively correlated with the annual percentage of skin test reactor cattle, suggesting a bovine TB reduction effect. In another treatment site, red deer (Cervus elaphus) M. bovis infection prevalence
decreased after wild boar culling. ADV seroprevalence in wild boar remained unaffected in the treatment sites. The reduction in wild boar TB was achieved despite no alternative M. bovis host being included in the culling strategy. Although culling alone is not a sustainable option for TB control in our area, wild boar culling could become a part of integrated control strategies including habitat and game management changes and vaccination, particularly if an initial short term but substantial reduction of host abundance and disease prevalence could contribute to increase the success likelihood of other control tools, or to reduce the total expenses.
