Abstract

Background and objectives: Staphylococcus aureus (S. aureus) is one of the most important pathogens, responsible for a range of infections. This study aimed to assess resistance patterns in S. aureus isolates obtained from certain private-sector laboratories against commonly used antimicrobial agents.

Materials and methods: The process involved collecting various samples from several private laboratories and then identifying S. aureus isolates using biochemical characterization. The antibiotic susceptibility of these isolates was determined by disc diffusion method. Furthermore, Rt-PCR was employed to identify two genes namely the methicillin/oxacillin resistance genes (mecA), and (SCCmec).

Results: The findings of the current study exhibited that females constituted a larger proportion of the participants (59.1%) compared to males (40.9%), with a mean participant age of 40.82 years. Gram-positive bacteria were more prevalent (71.3%) than Gram-negative bacteria (18.3%), with S. aureus being the most frequent isolate (60.9%). Urine samples represented the highest collected sample type (47.8%). Out of the 115 bacterial isolates, 85.2% exhibited multidrug resistance to antibiotics such as cefazolin, gentamicin, vancomycin, and ceftazidime. Clindamycin was the most effective antibiotic, with a sensitivity rate of 62.9%, followed by teicoplanin and meropenem, each with a sensitivity rate of 52.9%. Methicillin-resistant Staphylococcus aureus (MRSA) strains were susceptabile to vancomycin and teicoplanin. The methicillin/oxacillin resistant isolates showed significant association with mecA and SCCA genes.

Conclusion: This study highlighted the multi-drug resistance in S. aureus isolates, stressing the need for stringent antibiotic stewardship, continuous surveillance, and further research into alternative treatments, including novel antibiotics and combination therapy, to combat resistant strains.

约旦私营部门实验室中金黄色葡萄球菌分离株对常用抗生素的耐药性概况。
背景和目的:金黄色葡萄球菌(金黄色葡萄球菌)是最重要的病原体之一,负责一系列感染。本研究旨在评估从某些私营部门实验室获得的金黄色葡萄球菌分离株对常用抗菌剂的耐药性模式。材料和方法:该过程包括从几个私人实验室收集各种样品,然后使用生化表征鉴定金黄色葡萄球菌分离物。采用圆盘扩散法对分离菌株进行药敏试验。此外,采用Rt-PCR技术鉴定了甲氧西林/氧西林耐药基因(mecA)和(SCCmec)。结果:本研究结果显示,女性占参与者的比例(59.1%)高于男性(40.9%),参与者的平均年龄为40.82岁。革兰氏阳性菌(71.3%)多于革兰氏阴性菌(18.3%),其中以金黄色葡萄球菌(60.9%)最为常见。尿液样本为最高的样本类型(47.8%)。在115株细菌分离株中,85.2%对头孢唑林、庆大霉素、万古霉素和头孢他啶等抗生素表现出多重耐药。克林霉素是最有效的抗生素,敏感性为62.9%,其次是替柯planin和美罗培南,敏感性均为52.9%。耐甲氧西林金黄色葡萄球菌(MRSA)对万古霉素和替可普宁敏感。甲氧西林/氧西林耐药菌株显示与mecA和SCCA基因显著相关。结论:本研究强调了金黄色葡萄球菌分离株的多重耐药,强调需要严格的抗生素管理,持续监测,并进一步研究替代治疗方法,包括新型抗生素和联合治疗,以对抗耐药菌株。

期刊介绍: The Iranian Journal of Microbiology (IJM) is an international, multi-disciplinary, peer-reviewed journal that provides rapid publication of the most advanced scientific research in the areas of basic and applied research on bacteria and other micro-organisms, including bacteria, viruses, yeasts, fungi, microalgae, and protozoa concerning the development of tools for diagnosis and disease control, epidemiology, antimicrobial agents, clinical microbiology, immunology, Genetics, Genomics and Molecular Biology. Contributions may be in the form of original research papers, review articles, short communications, case reports, technical reports, and letters to the Editor. Research findings must be novel and the original data must be available for review by the Editors, if necessary. Studies that are preliminary, of weak originality or merely descriptive as well as negative results are not appropriate for the journal. Papers considered for publication must be unpublished work (except in an abstract form) that is not under consideration for publication anywhere else, and all co-authors should have agreed to the submission. Manuscripts should be written in English.
