The spread of carbapenem-resistant and is a global concern. The management of infections caused by multidrug resistance (MDR) isolates poses substantial clinical challenges in both hospitals and communities. This study aimed to investigate the genetic characteristics and variations of MDR and isolates. Bacterial identification and antibiotic susceptibility testing against 19 antibiotics were performed by standard methods. Whole genome sequencing (WGS) was carried out on eight carbapenem-resistant isolates using an Illumina MiSeq platform. The assembled draft genomes were annotated, then sequences were blasted against antimicrobial resistance (AMR) genes database. WGS detected several resistance genes mediating the production of β-lactamases, including carbapenems and extended-spectrum β-lactamase genes as , , , , , , , and ). Furthermore quinolone resistance including , , , , , , , , , and . In addition to aminoglycoside modifying enzymes genes (, ″, , , , and ), trimethoprim-sulfamethoxazole (), tetracycline ( and ), fosfomycin () resistance genes, while other genes were detected conferring chloramphenicol (, , and efflux pump ), macrolides resistance (, and quaternary ammonium efflux pump Bleomycin and colistin resistance genes were detected as and , respectively. Comprehensive analysis of MDR strains provided by WGS detected variable antimicrobial resistance genes and their precise resistance mechanism. WGS is essential for control and prevention strategies to combat the growing threat of AMR and the implementation of multifaceted interventions are needed.
耐碳青霉烯类[细菌]的传播是一个全球关注的问题。由多重耐药(MDR)菌株引起的感染管理在医院和社区都带来了重大的临床挑战。本研究旨在调查MDR[细菌]和[另一类细菌]菌株的遗传特征和变异情况。通过标准方法对19种抗生素进行细菌鉴定和药敏试验。使用Illumina MiSeq平台对8株耐碳青霉烯类菌株进行全基因组测序(WGS)。对组装的基因组草图进行注释,然后将序列与抗菌药物耐药性(AMR)基因数据库进行比对。WGS检测到了几种介导β-内酰胺酶产生的耐药基因,包括碳青霉烯类和超广谱β-内酰胺酶基因,如[列举多个基因名称]。此外还检测到喹诺酮耐药相关基因,如[列举多个基因名称]。除了氨基糖苷类修饰酶基因([列举多个基因名称])、甲氧苄啶-磺胺甲恶唑([相关基因名称])、四环素([相关基因名称])、磷霉素([相关基因名称])耐药基因外,还检测到其他赋予氯霉素([相关基因名称]、[相关基因名称]和外排泵[相关基因名称])、大环内酯类耐药([相关基因名称]和季铵盐外排泵[相关基因名称])的基因。博来霉素和黏菌素耐药基因分别检测为[相关基因名称]和[相关基因名称]。WGS对MDR菌株的综合分析检测到了可变的抗菌药物耐药基因及其精确的耐药机制。WGS对于应对AMR日益增长的威胁的控制和预防策略至关重要,并且需要实施多方面的干预措施。
