Final R=0.074(Rw=0.082) for 2662 unique reflections with I≥3σ(I). The V atom in the compound retains the tetrahedral geometry of the VS3O with S-V-S or S-V-O angles of 108.6(6)~110.3 (6)°.The cluster core [V2Cu6S6O2] of the compound can be regarded as two cluster cores [VCu3S3O] bonded by bondings of the Cu-Cu'(distances of 2.774(3)~2.707(5) A) and Cu-S (distances of 2.463(7)~2.396(9) A) with centrosymmetric. Atoms of the cluster core V2Cu6 form a distorted cube with the Cu Cu'or the V-Cu distances of 2. 774(3)~2. 707(5) A.展开更多
目的分析医院碳青霉烯耐药肺炎克雷伯菌(carbapenemase resistant K. pneumoniae,CRKP)尿路感染的分子流行病学特点,为临床科学防控提供实验室依据。方法选择2016年1-12月医院引起医院尿路感染的非重复CRKP菌株18株,采用多位点序列分析(...目的分析医院碳青霉烯耐药肺炎克雷伯菌(carbapenemase resistant K. pneumoniae,CRKP)尿路感染的分子流行病学特点,为临床科学防控提供实验室依据。方法选择2016年1-12月医院引起医院尿路感染的非重复CRKP菌株18株,采用多位点序列分析(MLST)方法进行分型,并使用PCR方法检测常见碳青霉烯酶基因(DNM、KPC、SME、VIM、GES、IMP、OXA-48)和多黏菌素耐药基因MCR-1等。结果 18株医院尿路感染CRKP菌株,KPC-2基因携带率为94.44%(17/18),其中一株同时携带KPC和MCR-1基因,MLST分型以ST11型为主(88.89%,16/18)。结论 CRKP引起的尿路感染患者,多年龄偏大,有保留导尿和高级别抗菌药物使用史,应该规范抗菌药物使用与加强消毒隔离措施,控制流行传播。展开更多
