Positive bacterial cultures from different clinical samples were identified using a VITEK®2 compact system and the antimicrobial susceptibility profile of different Gram-negative bacteria was analysed.
A total of 2489 clinical samples were collected and processed for culture during the period January 2013 to April 2017. Of 1103 pure bacterial cultures, 690 (62.6%) were Gram-negative bacteria. The antimicrobial susceptibility profile of Gram-negative bacterial strains revealed that 41.3% (n=285) were XDR and 8.1% (n=56) were PDR. Rates of colistin and tigecycline resistance were 16% and 51.9%, respectively.
This situation demands regular surveillance of antimicrobial resistance of Gram-negative bacteria and implementation of an efficient infection control programme.
使用VITEK®2紧凑型系统鉴定来自不同临床样品的阳性细菌培养物,并分析不同革兰氏阴性菌的抗微生物敏感性曲线。
在2013年1月至2017年4月期间,共收集并处理了2489个临床样品进行培养。在1103种纯细菌培养物中,690例(62.6%)为革兰氏阴性菌。革兰氏阴性菌菌株的抗菌敏感性曲线显示,XDR占41.3%(n=285),PDR占8.1%(n=56)。粘菌素和替加环素耐药率分别为16%和51.9%,分别。
这种情况需要定期监测革兰氏阴性菌的抗菌素耐药性,并实施有效的感染控制计划。
