Probing the die-off of Pacific oysters - PNAS Science Sessions
Description
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.
