Abstract
Nonconjugative plasmids encoding sulfanilamide (Sa) resistance were demonstrated at a high frequency in Shigella and Escherichia coli strains resistant to sulfanilamide. These Sa plasmids were all compatible with the standard plasmids used in compatibility testing. The sizes of seven Sa plasmids were measured by electron microscopy and ranged from 1.79 to 2.08 mum, corresponding to 3.5 to 3.9 megadaltons.
摘要
在对磺胺耐药的志贺氏菌和大肠杆菌菌株中，高频检出了编码磺胺（Sa）抗性的非接合质粒。这些Sa质粒与用于相容性测试的标准质粒均具有相容性。通过电子显微镜测定了7种Sa质粒的大小，范围在1.79至2.08μm之间，相当于3.5至3.9兆道尔顿。
