The screening for intestinal carriage of vancomycin-resistant Enterococcus spp. (VRE) among high risk patients in the Balkan region and molecular epidemiology of VRE is insufficiently investigated, yet it could be of key importance in infection control. The aim of this study was to provide baseline data on VRE intestinal carriage among high-risk patients in Serbian university hospitals, to determine the phenotypic/genotypic profiles of the isolated VRE, to obtain knowledge of local resistance patterns and bridge the gaps in current VRE surveillance. The VRE reservoir was investigated using stool samples from 268 inpatients. Characterization of isolated VRE stains consisted of BD Phoenix system, genotypic identification, glycopeptide and quinupristin–dalfopristin (Q–D) resistance probing, virulence gene (esp, hyl, efaA, asa1, gelE, cpd) detection and MLVA. Biofilm formation was evaluated by the microtiter plate method. VRE carriage prevalence among at-risk patients was 28.7%. All VRE strains were vanA positive multidrug-resistant Enterococcus faecium (VRfm), harboring ermB-1 (38.9%), esp (84%), efaA (71.2%), hyl (54.5%), asa1 (23.4%), gelE and cpd (11.6%) each. Ability of biofilm production was detected in 20.8%. Genetic relatedness of the isolates revealed 13 clusters, heterogeneous picture and 25 unique MTs profiles. The obtained prevalence of VRE intestinal carriage among high-risk inpatients in Serbia is higher than the European average, with high percentage of multidrug resistance. The emergence of resistance to Q–D is of particular concern. Close monitoring of pattern of resistance and strict adherence to specific guidelines are urgently needed in Serbia.

耐万古霉素肠球菌的肠道携带。塞尔维亚大学医院的高危患者:第一份监测报告

耐万古霉素肠球菌肠道携带的筛选 (VRE) 在巴尔干地区的高危患者中进行,VRE 的分子流行病学研究还不够充分,但它在感染控制中可能是至关重要的。本研究的目的是提供塞尔维亚大学医院高危患者肠道携带 VRE 的基线数据,以确定孤立 VRE 的表型/基因型特征,了解局部耐药模式并弥合当前 VRE 的差距监视。使用来自 268 名住院患者的粪便样本对 VRE 储库进行了研究。分离的 VRE 染色的表征包括 BD Phoenix 系统、基因型鉴定、糖肽和奎奴普丁-达福普汀 (Q-D) 抗性探测、毒力基因(esp、hyl、efaA、asa1、gelE、cpd) 检测和 MLVA。通过微量滴定板法评价生物膜形成。高危患者中 VRE 携带率为 28.7%。所有 VRE 菌株均为 vanA 阳性多药耐药粪肠球菌 (VRfm),含有 ermB-1 (38.9%)、esp (84%)、efaA (71.2%)、hyl (54.5%)、asa1 (23.4%)、gelE 和每个 cpd (11.6%)。检测到生物膜产生能力为 20.8%。分离株的遗传相关性揭示了 13 个簇、异质图片和 25 个独特的 MTs 配置文件。塞尔维亚高危住院患者 VRE 肠道携带率高于欧洲平均水平,多药耐药率高。对 Q-D 的抗性的出现尤其令人担忧。塞尔维亚迫切需要密切监测抵抗模式并严格遵守具体指导方针。通过微量滴定板法评价生物膜形成。高危患者中 VRE 携带率为 28.7%。所有 VRE 菌株均为 vanA 阳性多药耐药粪肠球菌 (VRfm),含有 ermB-1 (38.9%)、esp (84%)、efaA (71.2%)、hyl (54.5%)、asa1 (23.4%)、gelE 和每个 cpd (11.6%)。检测到生物膜产生能力为 20.8%。分离株的遗传相关性揭示了 13 个簇、异质图片和 25 个独特的 MTs 配置文件。塞尔维亚高危住院患者 VRE 肠道携带率高于欧洲平均水平,多药耐药率高。对 Q-D 的抗性的出现尤其令人担忧。塞尔维亚迫切需要密切监测抵抗模式并严格遵守具体指导方针。通过微量滴定板法评价生物膜形成。高危患者中 VRE 携带率为 28.7%。所有 VRE 菌株均为 vanA 阳性多药耐药粪肠球菌 (VRfm),含有 ermB-1 (38.9%)、esp (84%)、efaA (71.2%)、hyl (54.5%)、asa1 (23.4%)、gelE 和每个 cpd (11.6%)。检测到生物膜产生能力为 20.8%。分离株的遗传相关性揭示了 13 个簇、异质图片和 25 个独特的 MTs 配置文件。塞尔维亚高危住院患者 VRE 肠道携带率高于欧洲平均水平,多药耐药率高。对 Q-D 的抗性的出现尤其令人担忧。塞尔维亚迫切需要密切监测抵抗模式并严格遵守具体指导方针。
