| genotype diversity of escherichia coli isolates in natural waters determined by pfge and eric-pcr. | most library-dependent bacterial source tracking studies using escherichia coli (e. coli) have focused on strain diversity of isolates obtained from known human and animal faecal sources for library development. in contrast, this study evaluated the genotype variation of e. coli isolated from natural surface water using pulsed field gel electrophoresis (pfge) and enterobacterial repetitive intergenic consensus sequence polymerase chain reaction (eric-pcr) to better understand these naturally occ ... | 2007 | 17475306 |
