There has been a substantial rise in the number of vancomycin-resistant (VRSA) strains during the last several years. The proportion of vancomycin-resistant strains among isolated has risen steadily in recent years, with the first spike occurring in critical care units and thereafter in general hospital wards. isolates from urinary tract infection patients were studied for their prevalence and antibiotic resistance. From 292 urine samples, 103 bacterial strains (35.3%) were identified as . Various antibiotics were used to test the isolates' antibacterial resistance profiles. Antibiotic resistance to erythromycin was found in most bacterial isolates, whereas tobramycin antibiotic sensitivity was found in most of them. Vancomycin resistance was found in 23 of all isolates in this study. Analysis for β-lactamase found that 71% of isolates were positive in all isolates. There was a single plasmid with a molecular weight of 39.306 Kbp in five selected VRSA isolates that was subjected to plasmid analysis. There was evidence of vancomycin resistance among the isolates collected from UTI patients in this investigation. This vancomycin resistance pretenses a challenge in the treatment of infections and the need to precisely recognize persons who require last-resort medication such as tobramycin.
在过去几年中,耐万古霉素(VRSA)菌株的数量大幅上升。近年来,分离出的耐万古霉素菌株比例稳步上升,首次激增发生在重症监护病房,此后在综合医院病房也有出现。对尿路感染患者的分离株进行了流行率和抗生素耐药性研究。从292份尿液样本中,鉴定出103株细菌菌株(35.3%)为[原文此处缺失具体菌名]。使用各种抗生素测试分离株的抗菌耐药谱。大多数细菌分离株对红霉素耐药,而大多数对妥布霉素敏感。本研究中所有[原文此处缺失具体菌名]分离株中有23株对万古霉素耐药。β-内酰胺酶分析发现,所有分离株中71%的[原文此处缺失具体菌名]分离株呈阳性。对五个选定的VRSA分离株进行质粒分析,发现有一个分子量为39.306 Kbp的单一质粒。在本次调查中,从尿路感染患者收集的[原文此处缺失具体菌名]分离株中存在万古霉素耐药的证据。这种万古霉素耐药性给[原文此处缺失具体菌名]感染的治疗带来了挑战,并且需要精确识别需要使用妥布霉素等最后手段药物的患者。
