Serosurvey of Roe Deer, Chamois and Domestic Sheep in the Central Italian Alps

Roe deer (Capreolus capreolus), chamois (Rupicapra rupricapra rupicapra), and domestic sheep in the Orobie Alps, Italy, were serologically tested for antibodies to selected pathogens that may be transmitted across species. Antibodies against Brucella spp. and bovine herpesvirus 1 (roe deer and chamois only) were not detected in any species. In roe deer, antibodies were detected against Toxoplasma gondii (13%) and Neospora caninum (3%). Chamois tested positive for antibodies to T. gondii (5%), N. caninum (21%), bovine respiratory syncytial virus (BRSV) (41%), bovine parainfluenza type-3 virus (17%), pestiviruses (18%), and Mycoplasma conjunctivae (17%). In the sheep, particularly high antibody prevalence rates were found for T. gondii (78%), Chlamydophila spp. (20%), pestiviruses (90%), BRSV (82%), and M. conjunctivae (81%).
