WebThe electrophoretic trapping is a balance between the electrophoretic force (pulling the circular plasmid DNA against the trap) and diffusion (allowing the circular plasmid DNA to escape a trap). So, large circular molecules have a greater chance to get trapped than smaller DNA forms. WebTyping by PCR ribotyping and pulsed-field gel electrophoresis demonstrated clusters of carriers colonised by a single type in each of three groups, indicating that cross-transmission of C. difficile can occur in community settings.
