A total of 48 strains of the soil bacterium Rhizobium japonicum were screened for their response to several widely used antibiotics. Over 60% of the strains were resistant to chloramphenicol, polymyxin B, and erythromycin, and 47% or more of the strains were resistant to neomycin and penicillin G, when tested by disk assay procedures. The most common grouping of resistances in strains was simultaneous resistance to tetracycline, penicillin G, neomycin, chloramphenicol, and streptomycin (25% of all strains tested). The occurrence of multiple drug resistance in a soil bacterium that is not a vertebrate pathogen suggests that chemotherapeutic use of antibiotics is not required for the development of multiple drug resistance.
总共对48株土壤细菌日本根瘤菌进行了筛选,以检测它们对几种广泛使用的抗生素的反应。通过纸片扩散法检测时,超过60%的菌株对氯霉素、多粘菌素B和红霉素耐药,47%或更多的菌株对新霉素和青霉素G耐药。菌株中最常见的耐药组合是对四环素、青霉素G、新霉素、氯霉素和链霉素同时耐药(占所有测试菌株的25%)。在一种非脊椎动物病原体的土壤细菌中出现多重耐药性表明,多重耐药性的产生并不需要抗生素的化疗用途。
