Paul R. Bowser: Neilly Series Lecture





Bowser, professor of Aquatic and Animal Medicine at Cornell, will discuss "Viral Hemorrhagic Septicemia in Fish in the Great Lakes Basin." Viral Hemorrhagic Septicemia (VHS) is an emerging viral disease of fish in the Great Lakes ecosystem. In 2006, the virus was documented for the first time in New York State in round gobies in the St. Lawrence River. As a World Animal Health Organization Reportable Pathogen, the documentation of this virus has interstate and international trade implications for fish and fish products. In response to the finding, the USDA issued an Emergency Order that restricts the interstate movement of 37 species of fish within the 8 states bordering the Great Lakes and restricts the movement of the same 37 species of fish from Ontario and Quebec into the US. While VHS has a relatively long history in Europe, the disease found in the Great Lakes is behaving differently, having the capability to infect a large number of different fish species.

While most cases of VHS have been in fish originating from the Great Lakes, cases in fish from Conesus and Skaneateles Lakes have been found recently. A big concern is whether the virus will find its way into other bodies of water that are not part of the contiguous Great Lakes.
