Implication

PCV2b predominance in PCVAD tissues supports targeted genotyping; leaves open whether current vaccines require genotype-specific updates in swine herds.

Structured PICO

Population

1675 serum samples from clinically normal pigs (1177 PCV2 vaccinated, 378 non-vaccinated, 120 unknown vaccination status) and 100 lung samples from pigs diagnosed with PCV-associated disease (PCVAD)

Outcome

Prevalence of PCV2 genotypes (PCV2a and PCV2b)surrogate

PCV2b is more prevalent than PCV2a in PCVAD cases, and PCV2b circulation remains common in vaccinated herds.
