| use of barcoded pyrosequencing and shared otus to determine sources of fecal bacteria in watersheds. | while many current microbial source tracking (mst) methods rely on the use of specific molecular marker genes to identify sources of fecal contamination, these methods often fail to determine all point and nonpoint contributors of fecal inputs into waterways. in this study, we developed a new library-dependent mst method that uses pyrosequencing-derived shared operational taxonomy units (otus) to define sources of fecal contamination in waterways. a total 56,841 pyrosequencing reads of 16s rdna ... | 2010 | 20853824 |
| high diversity and abundance of antibiotic-resistant escherichia coli isolated from humans and farm animal hosts in jeonnam province, south korea. | the spread of antibiotics resistance among bacteria is a threat to human health. since south korea uses approximately 1.5 times more antibiotics than do other oecd countries, this is likely to impact the numbers and types of antibiotic-resistant bacteria found in the environment. in this study we examined feces from domesticated animals and humans for the diversity and abundance of antibiotic-resistant escherichia coli. abundant antibiotic-resistant e. coli were isolated from all the tested anim ... | 2010 | 20510439 |
