Summary
A malformed American bullfrog (Rana catesbeiana) metamorph with a smaller right eye was found to have frog virus 3 (FV3). This is the first report linking FV3 to anuran malformations.
Area of Science:
- Amphibian ecology and pathology
- Virology and molecular diagnostics
Background:
- Amphibian populations are crucial indicators of environmental health.
- Understanding amphibian diseases aids in conservation efforts.
Observation:
- A malformed American bullfrog (Rana catesbeiana) metamorph was captured in Tennessee.
- The specimen exhibited a significant size difference between its right and left eyes.
- Microscopic examination revealed orbital granulomas containing viral particles.
Findings:
- PCR and sequencing confirmed the presence of frog virus 3 (FV3).
- This is the first documented case of FV3 associated with an anuran malformation.
Implications:
- FV3 may play a role in causing developmental abnormalities in amphibians.
- Further research is needed to understand the pathogenesis of FV3-induced malformations.
- This finding highlights the importance of monitoring viral diseases in wild amphibian populations.
