Emerging cases of vancomycin-resistant enterococci (VRE) are detrimental for the patients. The current study aimed to ascertain the occurrence of VRE, their antibiogram and the genotype responsible for vancomycin resistance.
A total number of 2,958 clinical specimens were processed at Microbiology Department of the Alrazi Health Care, Lahore during the one year (2016-2017) using microbiological culture media, biochemical and serology. Antibiogram of enterococcal strains was performed using disc diffusion and E-test. ATCC 29212 was used as a quality control strain. The detection of genotypes was accomplished by multiplex PCR assay.
Out of the 147 enterococci, 139 (94.6%) were , and 8 (5.4%) were . Statistically significant associations of urine (p < 0.001), pus (p < 0.001) and wound swabs (p = 0.001) were observed with . A significant correlation of enterococcal infections (p = 0.05) was seen with female patients. Four (2.9%) strains of found to be VRE with (75%) and (25%) genotypes.
The emerging strains of VRE ( and genotype) in the current study are a potential menace for therapeutic failure, which left the physicians with only linezolid as a therapeutic option.
耐万古霉素肠球菌(VRE)新出现的病例对患者有害。本研究旨在确定VRE的发生率、它们的抗菌谱以及导致万古霉素耐药的基因型。
在一年时间(2016 - 2017年)里,拉合尔的阿尔拉齐医疗保健中心微生物科使用微生物培养基、生化和血清学方法对总共2958份临床标本进行了处理。使用纸片扩散法和E试验对肠球菌菌株进行抗菌谱检测。将ATCC 29212用作质量控制菌株。通过多重PCR检测法完成基因型的检测。
在147株肠球菌中,139株(94.6%)为[此处原文缺失相关内容],8株(5.4%)为[此处原文缺失相关内容]。观察到尿液(p < 0.001)、脓液(p < 0.001)和伤口拭子(p = 0.001)与[此处原文缺失相关内容]有统计学上的显著关联。女性患者的肠球菌感染有显著相关性(p = 0.05)。发现4株(2.9%)[此处原文缺失相关内容]菌株为VRE,其基因型为[此处原文缺失相关内容](75%)和[此处原文缺失相关内容](25%)。
本研究中VRE的新出现菌株([此处原文缺失相关内容]和[此处原文缺失相关内容]基因型)是治疗失败的潜在威胁,这使得医生只剩下利奈唑胺作为治疗选择。
