Genome-wide detection of conservative site-specific recombination in bacteria
Fig 5
Expression of CDR20291_3128 is consistent with phase variation.
Liquid culture samples from C. difficile R20291 and ∆3128::SNAP-tag were analyzed by light and fluorescence microscopy following staining with SNAP-Cell TMR-Star substrate. The left column shows the view of total cells in bright field light (BF), the middle column shows the SNAP-tag expressing cells pseudocolored in red, and the right column shows the merged pictures of BF and fluorescence.
