Fluoroquinolone-resistant突变体选择从金黄色葡萄球菌反恐怖主义中心8532 (F77),和两个GrlA F77的突变体与莫西沙星(F193和F194), sparfloxacin、氧氟沙星、左氧氟沙星和trovafloxacin grepafloxacin。F77的突变体选择、莫西沙星grepafloxacin和sparfloxacin优先选择突变gyrA (glu - 88 - - - >赖氨酸)。氧氟沙星和trovafloxacin选择最常见的突变grlA,赋予ser - 80替换。三个突变体F77的替换在GrlA(板式换热器- 80)和GyrA(赖氨酸- 88)。突变体的选择从F193 (GrlA板式换热器- 80),限制片段长度多态性分析gyrA显示,76/94在密码子突变84;这些都详细分析替代Ser - - >低浓缩铀。两个突变体选择grepafloxacin包含替换赖氨酸- 88。一个突变体选择trovafloxacin包含小说突变gyrA用g - 82 - - >半胱氨酸。突变体的选择从F194 (GrlA酪氨酸- 80),6/8 84 gyrA密码子的突变;其中3例含有亮氨酸。大多数代理商从F193突变体选择的麦克风和F194相似,无论选择的突变。 No mutants had any changes in grlB, and only one had a mutation in gyrB giving rise to the novel substitution Asp-437-->His. The mutations arising in first-step mutants were influenced by the fluoroquinolone used for selection. The phenotypes and genotypes of second-step mutants, derived from mutants with existing mutations in grlA, were similar, regardless of the selecting antibiotic.
