Previous studies have linked levels of porcine endogenous retroviruses (PERV)
with poor health and disease in pigs. To determine the levels of expression of
PERVs and their potential association with disease expression, real-time reverse
transcriptase (RT) PCR assays were used to assess PERV-ABC, PERV-C and
PERV-A/C levels in three commercial swine operations in the United States.
Pigs (n = 204) aged 3–25 weeks were screened, and all 369 serum samples
collected were found to be positive for PERV-ABC RNA as expected.
