A 10.6 megadalton plasmid was isolated from a virulent strain (NC-D) of Alcaligenes faecalis. Virulence and antibiotic sensitivity of this strain were compared with those characteristics of a mutant plasmid-free derivative, strain NC-D1. Strain NC-D1 was avirulent and lacked the streptomycin and sulfonamide resistances of the parent strain.
从粪产碱菌的一个强毒株（NC-D）中分离出了一个10.6兆道尔顿的质粒。将该菌株的毒力和抗生素敏感性与一个无质粒的突变衍生株NC-D1的这些特性进行了比较。菌株NC-D1无毒，并且缺乏亲本菌株的链霉素和磺胺抗性。
