    摘要:

    目的 对2例血流感染患者血培养标本分离的弧菌属进行鉴定和药敏试验,分析非O1群非O139群霍乱弧菌(NOVC)的微生物学特性,为霍乱弧菌感染的诊断和防控提供依据。 方法 通过基质辅助激光解吸电离飞行时间质谱(MALDI-TOF MS)、API细菌生化反应鉴定卡、VITEK 2 Compact鉴定仪和16S rRNA基因测序鉴定2株弧菌分离株,并进行血清学分型、毒力基因分子检测和耐药表型检测。 结果 2株菌株均鉴定为霍乱弧菌,血清学试验确定为NOVC,毒力基因ctxAB检测阴性;药敏试验显示1株菌对氨苄西林、阿奇霉素、多西环素和氯霉素敏感,对四环素和复方磺胺甲唑耐药,另一菌株对所有检测抗菌药物均敏感。 结论 NOVC所致的血流感染在中国少有报道,完善血培养标本分离霍乱弧菌的准确鉴定、分型和耐药表型检测,对诊断、治疗和防控霍乱弧菌感染具有重要价值。

    Abstract:

    Objective To identify and conduct antimicrobial susceptibility testing on Vibrio species isolated from blood culture specimens of two patients with bloodstream infection (BSI), analyze the microbiological characteristics of non-O1/non-O139 Vibrio cholerae (NOVC), and provide evidence for the diagnosis, prevention and control of Vibrio cholerae infection. Methods Two Vibrio strains were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), API bacterial biochemical reaction identification test strip, VITEK 2 Compact identification instrument and 16S rRNA gene sequencing. Serological typing, virulence gene molecular detection, and drug resistance phenotype detection were performed to the Vibrio strains. Results Two strains were identified as Vibrio cholerae, classified as NOVC by serological typing, and were negative for ctxAB virulence gene detection. Antimicrobial susceptibility testing showed that one strain was sensitive to ampici-llin, azi-thromycin, doxycycline and chloramphenicol, while resistant to tetracycline and trimethoprim-sulfametho-xazole. The other strain was sensitive to all tested antimicrobial agents. Conclusion BSI caused by NOVC is rarely reported in China. Accurate identification, typing and drug-resistant phenotype detection of Vibrio cholerae isolated from blood culture specimens are valuable for the diagnosis, treatment, prevention and control of Vibrio cholerae-associated infection.
