Molecular typing of Salmonella weltevreden and Salmonella chincol by pulsed-field gel electrophoresis (PFGE) and enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR)
Genomic DNA of Salmonella weltevreden (10 isolates from poultry, two isolates each from raw vegetables and river water) and S. chincol (15 isolates from poultry) were characterized by pulsed-field gel electrophoresis (PFGE) and enterobacterial repetitive intergenic consensus-polymerase chain reactio...

| Summary: | Genomic DNA of Salmonella weltevreden (10 isolates from poultry, two isolates each from raw vegetables and river water) and S. chincol (15 isolates from poultry) were characterized by pulsed-field gel electrophoresis (PFGE) and enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR) analysis. These isolates originated from a single location in Kajang, Selangor. The results of the PFGE and ERIC-PCR were analysed and comparisons were made using GelCompar software. ERIC-PCR with primers ERIC1R and ERIC2 discriminated the S. weltevreden into five clusters and two single isolates and S. chincol into two clusters and two single isolates at a similarity level of 80%, respectively. PFGE produced a single cluster and eight single isolates for S. weltevreden, and one cluster and 11 single isolates for S. chincol at a similarity level of 80% after digestion with the restriction enzyme XbaI, respectively. These results demonstrate that both PFGE and ERIC-PCR are suitable tools for molecular typing of the isolates examined. |
