Summary This study aimed to survey captive wild boars for antibodies against Porcine circovirus ‐2 ( PCV ‐2) in registered farms. Serum samples ( n = 1305) were collected from 90‐day‐old wild boars from 118 farms of the Brazilian South‐east region, including the states of M inas G erais and S ão P aulo, and S outh region, including the states of P araná, R io G rande do S ul and S anta C atarina. All herds (100%) presented reactive animals, in varying numbers and from low‐to‐high antibody titres, with the occurrence ranging from 82 to 89%. Considering farms, the average prevalence was of 84.9% ( P < 0.05) and ranged from 54.1 to 94.95%. Regarding the geographic regions studied, the prevalence was of 100%, with PCV 2 antibodies detected in wild boars of all regions. This study provides the first evidence of PCV 2 antibodies in captive wild boars in B razil.
