Epifluorescence microscopy of a Lactococcus lactis xerS mutant

Streptococci and Lactococci possess alternative Xer site-specific recombination machinery, phylogenetically unrelated to the classical XerCD/dif system, to resolve chromosome dimers (see Le Bourgeois et al.). The image shows epifluorescence microscopy of a Lactococcus lactis xerS mutant (kindly provided by Søren M. Madsen, Denmark), after staining with the LIVE/DEAD BacLight Viability Kit (Molecular Probes).
