Population density and distribution of the four native European wild Caprines (Rupicapra rupicapra, Rupicapra pyrenaica, Capra ibex, Capra pyrenaica) have increased in recent decades. The improved conservation status of this valuable wildlife, while a welcome event in general terms, is at the same time a matter of concern since, intuitively, frequent and tighter contacts with sympatric livestock imply a greater risk of cross-transmission of emerging and re-emerging pathogens, and offer unexpected opportunities for pathogens to spread, persist and evolve. This article recalls the transmissible diseases that are perceived in Europe to be of major significance from a conservation perspective, namely brucellosis (BRC) by Brucella melitensis, infectious kerato-conjunctivitis (IKC) by Mycoplasma conjunctivae, pestivirosis (PV) by the border disease virus strain 4 and mange by Sarcoptes scabiei. Special emphasis has been put on the epidemiological role played by small domestic ruminants, and on key knowledge needed to implement evidence-based prevention and control strategies. Remarkably, scientific evidence demonstrates that major demographic downturns in affected wild Caprinae populations in recent decades have often been triggered by pathogens cross-transmitted at the livestock/wildlife interface.
