title: DNA Is Packaged within Membrane-Derived Vesicles of Gram-Negative but Not Gram-Positive Bacteria.
abstract: Recently, DNA packaged within nuclease-resistant membrane vesicles of Neisseria gonorrhoeae and Borrelia burgdorferi was described. This study assayed 18 species of gram-negative and gram-positive eubacteria for nuclease-protected DNA associated with extracellular membrane vesicles. Vesicles from only the gram-negative bacteria contained nuclease-protected linear or supercoiled DNAs or both.
