WebTwo molecular typing methods, DNA macrorestriction analysis with XbaI resolved by pulsed-field gel electrophoresis (PFGE) and infrequent restriction site PCR (IRS-PCR) assay with adapters designed for XbaI and HhaI restriction sites, were used to investigate two clusters of hospital-acquired bacteraemia associated with multi-resistant Klebsiella pneumoniae … WebPulsed field gel electrophoresis (PFGE) This technique was developed by Shwartz and Cantor in 1984. DNA, being negatively charged moves towards anode in an electric field during electrophoresis. Since DNA is a large molecule, it would end up migrating to a single band. Hence, DNA is cut using specific restriction endonucleases. midweek match of the day
