Class 1 integron is the most ubiquitous platform among antibiotic resistance bacterial populations, including strains. This meta-analysis aimed to determine the antibiotic resistance conferred by class 1 integron conserved segments (CS); 3'-qacEΔ1 and sul1, and 5'-int1 in strains.
An intensive literature search of electronic databases for relevant studies from their starting dates up to April 2019 was conducted by two independent investigators. The electronic databases included; PubMed, Ovid Medline and Google Scholar databases. Only studies that determined antibiotic resistance conferred by class 1 integron in strains isolated from clinical and/or environmental samples using Polymerase Chain Reaction (PCR) assay were included in this study.
The random-effects model was selected and performed for all the studies included in this meta-analysis. Fourteen studies consisting of both qacEΔ1 and sul1, and int1 in the class 1 integron of strains were included. The proportions of class 1 integron 3'-CS and 5'-CS were 70.4 % (95%CI: 37.5-94.4) and 52 % (95% CI: 6.3-95.7) respectively.
The proportions of class 1 integron in strains significantly contributed to the antibiotic resistances, which are comparable to other gram-negative bacteria clinical isolates. Moreover, the 3'-CS qacEΔ1 and sul1 are highly involved in the antibiotic resistance in comparison to 5'-CS int1. Generally, the study findings provide a general view on antibiotic resistance conferred by class 1 integron in strains.
1类整合子是抗生素耐药细菌群体(包括菌株)中最普遍存在的平台。本荟萃分析旨在确定1类整合子保守片段(CS);3'-qacEΔ1和sul1,以及5'-int1在菌株中赋予的抗生素耐药性。
两名独立研究人员对电子数据库进行了深入的文献检索,以查找从起始日期至2019年4月的相关研究。电子数据库包括;PubMed、Ovid Medline和谷歌学术数据库。本研究仅纳入了那些使用聚合酶链反应(PCR)检测法确定从临床和/或环境样本中分离出的菌株中1类整合子赋予的抗生素耐药性的研究。
对本荟萃分析中纳入的所有研究选择并执行了随机效应模型。纳入了14项研究,这些研究涉及菌株1类整合子中的qacEΔ1和sul1以及int1。1类整合子3'-CS和5'-CS的比例分别为70.4%(95%CI:37.5 - 94.4)和52%(95%CI:6.3 - 95.7)。
菌株中1类整合子的比例对抗生素耐药性有显著贡献,这与其他革兰氏阴性菌临床分离株相当。此外,与5'-CS int1相比,3'-CS qacEΔ1和sul1与抗生素耐药性高度相关。总体而言,研究结果提供了关于菌株中1类整合子赋予的抗生素耐药性的总体观点。
