© 2018, EcoHealth Alliance. Tuberculosis (TB) in wild boar (Sus scrofa) may be affected by coinfections with other pathogens, such as porcine circovirus type 2 (PCV2). Therefore, sanitary measures focused on controlling PCV2 could be useful in reducing the impact of TB in this wild suid. The aim of this study was to explore whether vaccination against PCV2 targeting young animals affects TB prevalence and TB severity in wild boar. The study was conducted on a game estate in mid-western Spain. Seventy animals of ages ranging from 4 to 8 months were captured, individually identified, vaccinated against PCV2 and released, forming a vaccinated group. Not-captured animals cohabiting with the vaccinated wild boar constituted the control group. Animals from both groups were hunted between 2013 and 2016 and a TB diagnosis based on pathological assessment and microbiological culture was made in all of them. The effect of PCV2 vaccination on TB prevalence and severity was explored using generalized lineal models. Whereas TB prevalence was similar in vaccinated and control groups (54.55 vs. 57.78%), vaccinated animals showed less probabilities to develop generalized TB lesions. Furthermore, mean TB severity score was significantly lower in vaccinated animals (1.55 vs. 2.42) suggesting a positive effect of PCV2 vaccination.
