| identification of human enteric pathogens in gull feces at southwestern lake michigan bathing beaches. | ring-billed (larus delawarensis ord, 1815) and herring (larus argentatus pontoppidan, 1763) gulls are predominant species of shorebirds in coastal areas. gulls contribute to the fecal indicator burden in beach sands, which, once transported to bathing waters, may result in water quality failures. the importance of these contamination sources must not be overlooked when considering the impact of poor bathing water quality on human health. this study examined the occurrence of human enteric pathog ... | 2008 | 19096455 |
| 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 |
| bacteroidales diversity in ring-billed gulls (laurus delawarensis) residing at lake michigan beaches. | this study investigated the occurrence and diversity of bacteroidales fecal bacteria in gulls residing in the great lakes region. members of this bacterial order have been widely employed as human and bovine host-specific markers of fecal pollution; however, few studies have focused on gulls, which can be a major source of fecal indicator bacteria and pathogens at beaches. we found a low but consistent occurrence of bacteroidales in gulls at five beaches in three different counties spanning the ... | 2009 | 19151182 |
