1 Type E Botulism in the Great Lakes: a Widespread Concern -Alicia Pérez-Fuentetaja
2 Sites of botulism type E outbreaks Georgian Bay Rocke and Bollinger
3 Great Lakes: Affected organisms Birds; typically two major events: mid-to-late summer: terns, gulls and cormorants. during Fall migration: sandpipers and sanderlings. fish-eating birds such as loons, mergansers and grebes. mussel-eating ducks such as long-tailed ducks, scoters and scaup. Fish: freshwater drum, smallmouth bass, round gobies, lake sturgeon. Other: Mudpuppies (aquatic salamanders) animals.nationalgeographic.com
4 Bird mortality estimates (USGS) Year Lake Number Primary species Michigan >12,000 Gulls, Loons Michigan, Huron >1,800 Gulls, Loons Michigan, Huron ~2,500 Mergansers, Gulls, Loons Erie >25,000 Mergansers, Gulls, Loons 2002 Erie >25,000 Long tail ducks, Gulls Loons, Mergansers, Cormorants 2004 Ontario >2,000 Long tail ducks, Gulls Loons, Cormorants
5 What is type E botulism? Neuroparalytic disease. Caused by a toxin produced by Clostridium botulinum type E. Botulism is transmitted through diet. C. botulinum is an environmental microbe found in soils and sediments that requires: anaerobic conditions warm temperatures protein-rich substrates. NYSDEC Dunkirk Fisheries Unit

7 Dreissenid modification of the benthic environment Dreissenid druses and sediment beds provide habitat for C. botulinum: Feces and pseudofeces. Anaerobic environment: Decomposition (dead mussels, pseudofeces ) Sediment sheltering (shells from mussels)

20 Challenges and Future Directions The elusive detection of C. botulinum type E vegetative cells or toxin in environmental samples. Collaboration with the New York State Museum: development of a promising assay that can detect minute amounts (0.009 pg/ml of sample) of C. botulinum type E toxin from Lake Erie samples (1000 fold more sensitive than the expensive mouse bioassay).
