PORCINE CIRCO VIRUS

PORCINE CIRCO VIRUS

Porcine circovirus-associated disease (PCVAD) is caused by PCV2, a small circular single-stranded DNA virus of the Circoviridae family; in growing pigs, PCV2 is linked to systemic illness, enteritis, pneumonia, and PDNS, with subclinical infections reducing weight gain via immune effects.
