Hypothesis

To identify a candidate etiologic agent for turkey viral hepatitis.

Conclusion

The study identified a novel picornavirus as the likely cause of turkey viral hepatitis.

Supporting Evidence

  • High-throughput sequencing revealed picornavirus sequences in the livers of diseased poults.
  • Real-time PCR confirmed the presence of viral RNA in various tissues of affected turkeys.
  • Phylogenetic analysis indicated that the new virus is distinct from known picornaviruses.

Takeaway

Researchers found a new virus in sick turkeys that might be making them sick and causing them to die.

Methodology

Samples from diseased turkey poults were analyzed using high-throughput pyrosequencing and real-time PCR.

Limitations

The specific burden of turkey viral hepatitis could not be estimated with confidence.

Participant Demographics

Samples were collected from 8 commercial flocks in California, USA.
