Vancomycin-resistant enterococci (VRЕ) are recognized as important hospital pathogens which have become common in patients admitted to the intensive care units (ICUs). The purpose of this study was to evaluate the incidence of and the risk factors for colonization with VRE among ICU patients. A total of 91 patients who had duration of hospitalization more than 48 h and without infection caused by VRE or/and other microorganisms in the ICU at University Hospital, Pleven were screened for colonization with VRE. The following data were collected: demographic characteristics, clinical information and antimicrobials use. The statistical analysis was performed using SPSS version 27.0. Colonization with VRE was established in 22 patients and one was carrying two enterococcal species. A total of 23 VRE were isolated. The univariate analysis showed that the postoperative critical cares (p < 0.001), cardiovascular diseases (p = 0.009) and the presence of an endotracheal tube (p = 0.003) were risk factors for colonization with VRE. Also, the postoperative critical cares (p = 0.021) and cardiovascular diseases (p = 0.018) were confirmed as independent risk factor for VRE acquisition by multivariate analysis. The prevalence of VRE colonization among the ICU patients was relatively high (24.2%). Risk factors for acquisition of intestinal VRE were the postoperative cares, cardiovascular diseases and the presence of an endotracheal tube.

Background: Antimicrobial-resistant (AMR) pathogens represent an ongoing global health burden. Colonization is often a prerequisite for infection, but the risk of infection after AMR colonization is not well understood. Using population-level health administrative data, we sought to investigate the risk of infection with the same AMR organism after detection of colonization.

Vancomycin-resistant enterococci (VRE) are important pathogens in hospitalized patients; however, the factors involved in VRE colonization of hospitalized patients are not well characterized. Bacteriocins provide a competitive advantage to enterococci in experimental models of colonization, but little is known about bacteriocin content in samples derived from humans and even less is known about their dynamics in the clinical setting. To identify bacteriocins which may be relevant in the transmission of VRE, we present a systematic analysis of bacteriocin content in the genomes of 2,248 patient-derived isolates collected over a 6-year period from a single hospital system.

Background: To determine if colonisation with drug resistant organisms is associated with worse outcomes in patients who subsequently develop sepsis.
Methods: Retrospective study of patients with sepsis employing logistic regression and linear regression to determine the independent association of colonisation with adverse outcomes.
Results: Mortality was higher in patients colonized with VRE [501 of 1937 (26%) v.

Article Synopsis
- Vancomycin exposure is linked to an increased risk of colonization by vancomycin-resistant enterococci (VRE), particularly through oral administration, which was examined in this retrospective study.
- The study analyzed data from a large hospital in South Korea over a ten-year period and found a significant correlation between oral vancomycin use and the incidence of hospital-acquired VRE.
- The findings underscore the importance of implementing antibiotic stewardship strategies to manage oral vancomycin use and prevent the spread of VRE in healthcare settings.
