The incidence of tobramycin-resistant, gentamicin-susceptible Serratia species at the Minneapolis Veterans Administration Medical Center decreased from an average 42.1 to 2.5% (P less than 0.001) during a 4.5-year period despite the predominant use of amikacin. These organisms were shown to express a 6'-N-acetyltransferase-modifying enzyme (EC 2.3.1.82). Resistance was not shown to be plasmid mediated.
在明尼阿波利斯退伍军人管理局医疗中心,尽管主要使用阿米卡星,但在4.5年的时间里,对妥布霉素耐药、对庆大霉素敏感的沙雷氏菌属的发生率从平均42.1%降至2.5%(P<0.001)。这些微生物被证明表达一种6'-N-乙酰转移酶修饰酶(EC 2.3.1.82)。耐药性并非由质粒介导。
