Laboratory Investigation of Salmonella enterica serovar Poona Outbreak in California: Comparison of Pulsed-Field Gel Electrophoresis (PFGE) and Whole Genome Sequencing (WGS) Results
Conclusions
Real-time PFGE and WGS genotyping results from this Salmonella Poona outbreak provided concordant assignment of isolates to the outbreak cluster by both methods. However, the WGS allowed for a more unequivocal determination of the genetic relatedness of the isolates than PFGE. WGS provided additional information regarding MLST type, pathogenicity genes, and bacteriophage content of the isolates. WGS data obtained independently at two laboratories showed complete agreement.
