| occurrence and growth characteristics of escherichia coli and enterococci within the accumulated fluid of the northern pitcher plant (sarracenia purpurea l.). | sarracenia purpurea l., a carnivorous bog plant (also known as the pitcher plant), represents an excellent model of a well-defined, self-contained ecosystem; the individual pitchers of the plant serve as a microhabitat for a variety of micro- and macro-organisms. previously, fecal indicator bacteria (escherichia coli and enterococci) were shown as incidental contaminants in pitcher fluid; however, whether their occurrence in pitcher fluid is incidental or common has not been established. the pur ... | 2005 | 16462861 |
| environmental occurrence of the enterococcal surface protein (esp) gene is an unreliable indicator of human fecal contamination. | the enterococcal surface protein (esp) gene found in enterococcus faecalis and e. faecium has recently been explored as a marker of sewage pollution in recreational waters but its occurrence and distribution in environmental enterococci has not been well-documented. if the esp gene is found in environmental samples, there are potential implications for microbial source tracking applications. in the current study, a total of 452 samples (lake water, 100; stream water, 129; nearshore sand, 96; and ... | 2008 | 19031895 |
