Hypothesis

Is there a novel Borna virus associated with proventricular dilatation disease in birds?

Conclusion

The study identified two strains of a novel Borna virus in birds diagnosed with proventricular dilatation disease.

Supporting Evidence

  • RNA sequencing revealed 96,698 reads related to Borna disease virus.
  • Real-time PCR confirmed the presence of the virus in the brains and other organs of affected birds.
  • Sequence analysis indicated at least two different strains of the virus.

Takeaway

Scientists found a new virus in sick birds that might be causing their illness.

Methodology

RNA was extracted from the brains of birds and analyzed using high-throughput sequencing and real-time PCR.

Limitations

The study did not determine if the virus directly causes proventricular dilatation disease.

Participant Demographics

The birds studied were captive animals from California, USA.
