Evaluation of the Effects of the Algal Nuisance Cladophora on E.coli and Beach Closures

This project's overarching goal is to determine if E. coli   associated with Cladophora mats influences beach closures in the   Great Lakes. This multi-institutional, interdisciplinary team will   pursue this broad objective by addressing the following specific   objectives:  1) Determine spatial and temporal effects of elevated Cladophora   levels on the relative abundance of E. coli and other indicator   bacteria (i.e., Enterococci) in proximity to bathing beaches.   Underlying hypothesis (H1): Cladophora mats contribute to the   background level of indicator organisms at recreational beaches.   2) Determine if populations of E. coli found in Cladophora mats   (both floating and on-shore) are transient or clonally derived.   Underlying hypothesis (H2): Cladophora mats provide a suitable   environment for the long-term survival and replication of E. coli.   3) Determine if Cladophora mats harbor pathogenic microorganisms   (Campylobacter, Salmonella, and Shigella) in higher densities and   frequencies than surrounding lake water. Underlying hypothesis (H3):   Cladophora mats provide an environment that leads to   increased/prolonged survival and growth of potential bacterial   pathogens in lake water.    (algae); (cladophora); (eutrophication); (algal blooms); (algal   bloom); (bacteria); (beach); (coliform); (Door county); (genetic);   (Lake Michigan); (Lake Superior); (Lake Erie); (pathogen);   (Wisconsin); (beach closures); (beach closings); (beach closure);   (beach closing)
