Abstract
Sixteen strains from the six serogroups of Legionella pneumophila were examined for the presence of extrachromosomal genetic elements by a modified cleared lysate procedure, dye-buoyant centrifugation, and agarose gel electrophoresis. Two strains, Atlanta-1 and Atlanta-2 from serogroup II, each contained a plasmid of cryptic function with a molecular weight of ca. 30 megadaltons.
摘要
通过改良的清亮裂解物程序、密度梯度离心和琼脂糖凝胶电泳，对嗜肺军团菌六个血清群中的16个菌株进行了染色体外遗传元件的检测。血清群II中的两个菌株，亚特兰大-1和亚特兰大-2，各自含有一个功能未知的质粒，分子量约为30兆道尔顿。
