| escherichia coli populations in great lakes waterfowl exhibit spatial stability and temporal shifting. | populations of escherichia coli from juvenile and adult ring-billed gulls, juvenile common terns, and adult canada geese were sampled over 6 years at five locations on lake superior (duluth, mn, and wisconsin) and lake michigan (wisconsin, illinois, and indiana) to determine the extent of spatial and temporal variability in e. coli strains. strain identity was determined using horizontal fluorophore-enhanced repetitive element palindromic dna fingerprinting. multivariate statistics were used to ... | 2009 | 19139226 |
