ICU shows increasing incidence of infection associated with the use of invasive procedures for the diagnostic purpose as well as the indiscriminate use of antibiotics. and are "very successful" pathogen and the emergence of the Metallo-β-Lactamases (MBL) is becoming a therapeutic challenge.
To isolate the Gram negative bacilli from the ICU samples. To identify the metallo betalactamase producers and to detect the gene presence among the and .
The Nonfermenting Gram negative bacilli isolates from the ICU samples were taken over for 5 years (2009-2014) in a tertiary care hospital.
The isolates of and were confirmed by API analyser and processed according to standard procedures. Detection of the MBL producers were done by E strip method and subjected for gene detection by PCR method.
In our study a total of 195 isolates of were obtained from various ICU. Of these MBL producers, 26 % were and 25 % were . The subtypes of MBL producing were 26%. The predominant gene coding for MBL activity in were found to be gene 11.9%. The gene accession numbers were KF975367, KF975372.
We have to control the development and dissemination of these superbugs among the ICU's.
重症监护病房(ICU)中,因诊断目的进行侵入性操作以及滥用抗生素导致感染发生率不断上升。[具体细菌名称1]和[具体细菌名称2]是“非常成功”的病原体,金属β-内酰胺酶(MBL)的出现正成为一个治疗挑战。
从ICU样本中分离革兰氏阴性杆菌。鉴定产金属β-内酰胺酶的菌株,并检测[具体细菌名称1]和[具体细菌名称2]中[具体基因名称]的存在情况。
在一家三级护理医院,对5年(2009 - 2014年)间从ICU样本中分离出的非发酵革兰氏阴性杆菌进行研究。
通过API分析仪确认[具体细菌名称1]和[具体细菌名称2]的分离株,并按照标准程序进行处理。采用E试条法检测产MBL的菌株,并通过PCR法进行[具体基因名称]检测。
在我们的研究中,共从各个ICU获得了195株[具体细菌名称1]分离株。其中,产MBL的菌株中,[具体细菌名称1]占26%,[具体细菌名称2]占25%。产MBL的[具体细菌名称1]的亚型占26%。在[具体细菌名称1]中,编码MBL活性的主要基因是[具体基因名称],占11.9%。基因登录号为KF975367、KF975372。
我们必须控制这些超级细菌在ICU中的发展和传播。
