Abstract

BACKGROUND

The high prevalence of virulence-associated genes observed in isolates underscores the pathogenic potential of this bacterium. The presence of these genes confers enhanced survival, evasion of host defenses, and increased virulence. In this study, we investigate the presence and distribution of genes associated with virulence and assess the antimicrobial susceptibility patterns in clinical isolates of .

MATERIALS AND METHOD

This research focused on examining the 50 multi-drugs resistant (MDR) strains that were included in this investigation. The identification of these strains was validated using Oxa-51. The presence of the and genes was determined through conventional PCR techniques.

RESULTS

The results derived from Oxa-51 PCR confirmed the identification of all 50 selected strains of . Additionally, both the and genes were successfully identified in 82% of the MDR strains.

CONCLUSION

Moreover, the varying antibiotic resistance patterns highlight the challenge in treating infections effectively. Strategies such as combination therapy, antimicrobial stewardship, and infection control measures should be considered to combat this multidrug-resistant pathogen.

摘要

背景

在分离株中观察到的毒力相关基因的高流行率凸显了这种细菌的致病潜力。这些基因的存在赋予了更强的生存能力、逃避宿主防御的能力以及更高的毒力。在本研究中,我们调查了与毒力相关的基因的存在和分布,并评估了临床分离株的抗菌药敏模式。

材料与方法

本研究聚焦于检测纳入本调查的50株多重耐药(MDR)菌株。使用Oxa-51验证这些菌株的鉴定。通过常规PCR技术确定和基因的存在。

结果

来自Oxa-51 PCR的结果证实了所有50株选定菌株的鉴定。此外,在82%的MDR菌株中成功鉴定出和基因。

结论

此外,不同的抗生素耐药模式凸显了有效治疗感染的挑战。应考虑联合治疗、抗菌药物管理和感染控制措施等策略来对抗这种多重耐药病原体。
