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.
摘要
最近，描述了淋病奈瑟菌和伯氏疏螺旋体的核酶抗性膜泡内包裹的 DNA。本研究检测了 18 种革兰氏阴性和革兰氏阳性真细菌，以检测与细胞外膜泡相关的核酶保护 DNA。只有革兰氏阴性细菌的囊泡中含有核酶保护的线性或超螺旋 DNA 或两者兼有。
