从一名患有严重伤口感染的 63 岁女性体内分离出的化脓性链球菌分离株被发现对氟喹诺酮类药物具有高度耐药性(左氧氟沙星 MIC > 或 = 32 mg/L)。 DNA 扩增和测序揭示了 gyrA 中的丝氨酸 81 替换为苯丙氨酸,以及 parC 中的三个替换:丝氨酸 79 替换为苯丙氨酸,天冬氨酸 91 替换为天冬酰胺,丝氨酸 140 替换为脯氨酸。据我们所知,这是欧洲国家首次报告具有高水平氟喹诺酮耐药性的化脓性链球菌临床分离株。
An isolate of Streptococcus pyogenes isolated from a 63-year-old woman with a serious wound infection was found to be highly resistant to fluoroquinolones (levofloxacin MIC > or = 32 mg/L). DNA amplification and sequencing revealed a serine-81 to phenylalanine substitution in gyrA and three substitutions in parC: serine-79 to phenylalanine, aspartic acid-91 to asparagine, and serine-140 to proline. To our knowledge, this is the first report from a European country of a clinical isolate of S. pyogenes with high-level fluoroquinolone resistance.
