Dam-like methylation in legionellae.


:The chromosomal DNA of a variety of legionellae, including clinical, environmental, and plasmid-containing strains, was examined for evidence of Dam-like methylation. It was found that Dam-like methylation was present in all the strains examined regardless of their origin or plasmid content.
