Introduction Hospital-acquired or nosocomial infections caused by the rapidly emerging bacteria vancomycin-resistant enterococci can be dangerous and even fatal. Therefore, this study aimed to investigate the presence of enterococci in various clinical specimens along with their vancomycin resistance status and biofilm-producing capabilities. Methods A total of 164 species were isolated and further included in this study. Isolation and identification were done by the standard bacteriological procedure, antibiotic susceptibility testingwas done by clinical laboratory standard guidelines, and biofilm production test was done by microtiter plate methods. Results Among the total of 164 isolates, constituted 60.97% and constituted 39.02%. Maximum isolates were from urine samples. The prevalence of vancomycin-resistant was 6.70%, and 18.29% of isolates were biofilm producers. The sensitivity among the biofilm producers was maximum for linezolid (87.33%), followed by teicoplanin (86.43%) and vancomycin (79.64%). Conclusion High prevalence of enterococci was found in urine samples andbiofilm producers isolates were more antibiotic-resistant than non-biofilm producers.
引言 由迅速出现的耐万古霉素肠球菌引起的医院获得性或医院感染可能很危险,甚至会致命。因此,本研究旨在调查各种临床标本中肠球菌的存在情况及其耐万古霉素状态和生物膜形成能力。方法 共分离出164种菌株并进一步纳入本研究。通过标准细菌学程序进行分离和鉴定,按照临床实验室标准指南进行抗生素敏感性测试,通过微量滴定板法进行生物膜形成测试。结果 在总共164株分离株中,[此处原文信息缺失]占60.97%,[此处原文信息缺失]占39.02%。分离株最多来自尿液样本。耐万古霉素[此处原文信息缺失]的患病率为6.70%,18.29%的[此处原文信息缺失]分离株是生物膜形成菌。生物膜形成菌中对利奈唑胺的敏感性最高(87.33%),其次是替考拉宁(86.43%)和万古霉素(79.64%)。结论 在尿液样本中发现肠球菌的患病率很高,并且生物膜形成菌分离株比非生物膜形成菌更具耐药性。
