Abstract

Forty-three strains of Erysipelothrix rhusiopathiae, isolated from pigs with chronic swine erysipelas, were examined for the presence of plasmid DNA by agarose gel electrophoresis and electron microscopy. Seven of these strains were found to contain plasmids of which number were varied from 1 to 6. The plasmids ranged from 1.4 to 86 kb in size. This is the first reported evidence for plasmid DNA in E. rhusiopathiae. The functions of the plasmids are unknown at present.

摘要

从患有慢性猪丹毒的猪中分离出43株猪红斑丹毒丝菌，通过琼脂糖凝胶电泳和电子显微镜检查其质粒DNA的存在情况。发现其中7株含有质粒，质粒数量从1到6不等。质粒大小在1.4至86 kb之间。这是首次报道猪红斑丹毒丝菌中存在质粒DNA的证据。目前质粒的功能尚不清楚。
