Abstract

Quinolone-resistant Streptococcus agalactiae bacteria were recovered from single-patient isolates and found to contain mutations in the gyrase and topoisomerase IV genes. Pulsed-field gel electrophoresis demonstrated that four isolates from the same long-term care facility were closely related; in seven cases, quinolone-resistant Haemophilus influenzae and S. agalactiae bacteria were isolated from the same patient.

摘要

耐喹诺酮的无乳链球菌从单患者分离株中分离得到,并发现其gyrase和拓扑异构酶IV基因存在突变。脉冲场凝胶电泳显示,来自同一长期护理机构的4株分离株密切相关;在7例病例中,耐喹诺酮的流感嗜血杆菌和无乳链球菌从同一患者体内分离得到。
