Recently i did PFGE and WGS comparison with the same set of E coli strains.
In my mind, if PFGE give two different pulsotypes, it is sure that strains are not the same. But when i did WGS, i found the same HC5 in cGMLST for some strains.
First case : there is 1 band difference in PFGE but no difference in HC5 clusterisation.
Second case : PFGE profiles are completely different this time but strains are clusterised in the same HC5.
What could be the explanation to these results?
