Abstract

A group H1 R factor encoding resistance to chloramphenicol, streptomycin, sulfonamide, and tetracycline was transferred into Salmonella typhimurium LT-2. The virulence of LT-2 for mice, as assessed by intraperitoneal 50% lethal dose and the number of organisms in the spleen, was not affected by the R factor. On the other hand, the R factor conferred resistance in mouse infections to therapy with chloramphenicol and trimethoprim plus sulfamethoxazole.

摘要

一种编码对氯霉素、链霉素、磺胺类药物和四环素耐药性的H1型R因子被转移到鼠伤寒沙门氏菌LT-2中。通过腹腔注射50%致死剂量和脾脏中的细菌数量评估,LT-2对小鼠的毒力不受R因子的影响。另一方面,R因子使小鼠感染时对氯霉素以及甲氧苄啶加磺胺甲恶唑的治疗产生耐药性。
