Abstract

The study of 3,237 Sh. flexneri strains isolated in Bulgaria revealed that 50.72% of them were resistant to antibiotics. 95.88% of the antibiotic-resistant strains were found to have R factor of incompatibility groups F, I or N. The plasmids of incompatibility group F had the property fin+, and the plasmids of groups I and N had the property fin-. R plasmids were divided into 4 groups by their ability for phage restriction.

摘要

对在保加利亚分离出的3237株福氏志贺氏菌菌株的研究表明，其中50.72%对抗生素耐药。发现95.88%的耐药菌株具有不相容群F、I或N的R因子。不相容群F的质粒具有fin+特性，而I群和N群的质粒具有fin-特性。R质粒根据其噬菌体限制能力分为4组。
