Agarose gel electrophoresis was employed to screen nine strains of Legionella-like bacteria and one strain of Legionella pneumophila for the presence of extrachromosomal deoxyribonucleic acid. Cryptic plasmids with molecular weights ranging from 46.6 x 10(6) to 59.8 x 10(6) were found in three of the isolates examined.
采用琼脂糖凝胶电泳法筛选9株类军团菌和1株嗜肺军团菌,以检测其是否存在染色体外脱氧核糖核酸。在所检测的分离株中,有3株发现了分子量范围为46.6×10⁶至59.8×10⁶的隐蔽质粒。
