| a comparison of box-pcr and pulsed-field gel electrophoresis to determine genetic relatedness of enterococci from different environments. | genetic relatedness of enterococci from poultry litter to enterococci from nearby surface water and groundwater in the lower fraser valley regions of british columbia, canada was determined. a new automated box-pcr and pulsed-field gel electrophoresis (pfge) were used to subtype enterococcal isolates from broiler and layer litter and surface and groundwater. all surface water samples (n = 12) were positive for enterococci, as were 11% (3/28) of groundwater samples. enterococcus faecium (n = 90) ... | 2012 | 22383122 |
