Seventy-five clinical isolates of Clostridium difficile from Shanghai and 80 from Stockholm were investigated. The prevalence of toxin A-negative, toxin B-positive isolates of C. difficile among isolates from Shanghai (33.3%) was significantly higher than among isolates from Stockholm (0%). Both sets of isolates were fully susceptible to metronidazole and vancomycin. However, the MICs of fluoroquinolones, erythromycin-clindamycin, tetracycline, rifampin and fusidic acid were significantly higher for the Shanghai isolates than for the Stockholm isolates. Thirty-three PCR ribotypes were identified; a dominant clone, 017, accounted for 18.7% of Shanghai isolates, whereas clone 005 dominated among Stockholm isolates, accounting for 11.3%. Strains 027 and 078 were not detected. No outbreak occurred during the study period.
对来自上海的 75 株艰难梭菌临床分离株和来自斯德哥尔摩的 80 株艰难梭菌临床分离株进行了研究。上海分离株中毒素 A 阴性、毒素 B 阳性的艰难梭菌的流行率(33.3%)显著高于斯德哥尔摩分离株(0%)。两组分离株均对甲硝唑和万古霉素完全敏感。然而,上海分离株对氟喹诺酮类、红霉素-克林霉素、四环素、利福平和夫西地酸的 MIC 值明显高于斯德哥尔摩分离株。鉴定出 33 种 PCR 核糖体分型;一个优势克隆,017,占上海分离株的 18.7%,而克隆 005在斯德哥尔摩分离株中占主导地位,占 11.3%。未检测到菌株 027 和 078。在研究期间未发生暴发。
