In Hong Kong, ParC changes among high-level quinolone-resistant Neisseria gonorrhoeae (QRNG) isolates at Ser-87-->Arg were associated with a higher level of resistance than a Ser-87-->Ile alteration. Two previously undescribed mutations in clinical isolates occurring in gyrA, conferring Ala-92-->Pro and Asp-95-->Tyr changes, were detected. Nine different outer membrane lipoprotein (Lip) repeat classes-11 to 19 repeats-were identified, with repeat lengths of 16 and 17 the most common, indicating considerable strain diversity.
在香港，高水平耐喹诺酮淋病奈瑟菌（QRNG）分离株中，ParC基因第87位丝氨酸（Ser）突变为精氨酸（Arg）与比第87位丝氨酸突变为异亮氨酸（Ile）更高水平的耐药性相关。在临床分离株中检测到gyrA基因发生了两个先前未描述的突变，导致第92位丙氨酸（Ala）变为脯氨酸（Pro）以及第95位天冬氨酸（Asp）变为酪氨酸（Tyr）。鉴定出9种不同的外膜脂蛋白（Lip）重复类别——11至19个重复——其中重复长度为16和17的最为常见，这表明菌株具有相当大的多样性。
