Probing the die-off of Pacific oysters
A giant virus associated with oyster aquaculture mortality Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us. In this episode, Curtis Suttle and Kevin Xu Zhong explain how a previously unidentified virus may be connected to mass die-offs of farmed Pacific oysters. In this episode, we cover: • [00:00] Introduction • [01:03] Environmental virologist Curtis Suttle introduces the importance of the Pacific oyster to aquaculture. • [01:42] Suttle describes mass mortality events, including one he witnessed. • [02:42] Environmental microbiologist Kevin Xu Zhong talks about the methods used to identify the Pacific Oyster Nidovirus 1. • [03:53] Zhong describes the notable features of the nidovirus. • [05:19] Zhong and Suttle explain how the nidovirus merits designation of a nidovirus family. • [06:25] Suttle explores the takeaways for oyster farmers and regulators. • [08:15] He lists the caveats and limitations of the study. • [09:40] Conclusion.
