摘要

B群链球菌(GBS)是一种能够引起尿路感染(uti)的泌尿病原体,尽管其在男性患者中的作用尚未明确。本研究旨在探讨泌尿系统症状男性患者分离的GBS菌株的荚膜血清型及其克隆关系。对阿达纳市医院收治的男性患者分离的69株GBS进行了分析。胶囊血清型采用多重PCR (Thermo Fisher Scientific, USA)检测,克隆关系采用脉冲场凝胶电泳(PFGE)检测(Bio-Rad, USA)。最常见的胶囊血清型是Ib (n = 28, 40.6%)、V (n = 23, 33.3%)和III (n = 18, 26.1%)。所有分离株均对氨苄西林和万古霉素敏感。环丙沙星耐药率为69.5%,红霉素为30.4%,克林霉素为24.6%,四环素为11.5%。PFGE分析显示,在不同日期采集的来自不同患者的两个分离株100%相同,表明可能存在克隆传播。总之,尽管GBS相关的uti在男性患者中并不常见,但本研究获得的数据为未来该人群中GBS的流行病学研究提供了有价值的见解。

Capsule typing and clonal relationships of group B streptococci isolated from male patients diagnosed with urinary tract infection.

Group B streptococcus (GBS) is a uropathogen capable of causing urinary tract infections (UTIs), although its role in male patients is not well characterized. This study aimed to investigate the capsule serotypes and clonal relationships of GBS strains isolated from male patients with urinary symptoms. A total of 69 GBS isolates from male patients admitted to Adana City Hospital were analyzed. Capsule serotypes were determined by multiplex PCR (Thermo Fisher Scientific, USA), and clonal relationships were assessed using pulsed-field gel electrophoresis (PFGE) (Bio-Rad, USA). The most common capsule serotypes identified were Ib (n = 28; 40.6%), V (n = 23; 33.3%), and III (n = 18; 26.1%). All isolates were susceptible to ampicillin and vancomycin. Resistance rates were 69.5% for ciprofloxacin, 30.4% for erythromycin, 24.6% for clindamycin, and 11.5% for tetracycline. PFGE analysis revealed that two isolates from different patients, collected on separate dates, were 100% identical, indicating possible clonal spread. In conclusion, although GBS-related UTIs are uncommon in male patients, the data obtained in this study provide valuable insights for future epidemiological research on GBS in this population.

期刊介绍: Unlike journals which specialize ever more narrowly, Folia Microbiologica (FM) takes an open approach that spans general, soil, medical and industrial microbiology, plus some branches of immunology. This English-language journal publishes original papers, reviews and mini-reviews, short communications and book reviews. The coverage includes cutting-edge methods and promising new topics, as well as studies using established methods that exhibit promise in practical applications such as medicine, animal husbandry and more. The coverage of FM is expanding beyond Central and Eastern Europe, with a growing proportion of its contents contributed by international authors.
