TY - JOUR. T1 - Vancomycin-resistant and vancomycin-sensitive enterococcal bacteremia. T2 - A comparison of clinical features and outcomes. AU - Lucas, G.. AU - Lechtzin, N.. AU - Puryear, W.. AU - Yau, L.. AU - Moore, R. D.. PY - 1997/12/1. Y1 - 1997/12/1. N2 - Multidrug-resistant enterococcus is emerging as a major nosocomial threat in the 1990s. In 1993, 14% of enterococcal isolates from intensive care units were resistant to vancomycin (VRE). Infections caused by such isolates are often unbeatable with commonly employed antibiotics. The goal of our study was to elucidate risk factors for the development of VRE bacteremia and to better understand the morbidity and mortality associated with VRE. Chart reviews were performed on 93 hospitalized patients who acquired VRE bacteremia between 1991 and 1996. Identical data points were recorded from 101 control patients with vancomycin-sensitive enterococcal (VSE) bacteremia hospitalized during the same period. In comparison with VSE, VRE patients ...
The Drosophila immune system discriminates between different classes of infectious microbes and responds with pathogen-specific defense reactions via the selective activation of the Toll and the immune deficiency (Imd) signaling pathways. The Toll pathway mediates most defenses against Gram-positive bacteria and fungi, whereas the Imd pathway is required to resist Gram-negative bacterial infection. Microbial recognition is achieved through peptidoglycan recognition proteins (PGRPs); Gram-positive bacteria activate the Toll pathway through a circulating PGRP (PGRP-SA), and Gram-negative bacteria activate the Imd pathway via PGRP-LC, a putative transmembrane receptor, and PGRP-LE. Gram-negative binding proteins (GNBPs) were originally identified in Bombyx mori for their capacity to bind various microbial compounds. Three GNBPs and two related proteins are encoded in the Drosophila genome, but their function is not known. Using inducible expression of GNBP1 double-stranded RNA, we now demonstrate ...
Background: Increasing bacterial infections as well as a rise in bacterial resistance call for the development of novel and safe antimicrobial agents without inducing bacterial resistance. Nanoparticles (NPs) present some advantages in treating bacterial infections and provide an alternative strategy to discover new antibiotics. Here, we report the development of novel self-assembled fluorescent organic nanoparticles (FONs) with excellent antibacterial efficacy and good biocompatibility.. Methods: Self-assembly of 1-(12-(pyridin-1-ium-1-yl)dodecyl)-4-(1,4,5-triphenyl-1H-imidazol-2-yl)pyridin-1-ium (TPIP) in aqueous solution was investigated using dynamic light scattering (DLS) and transmission electron microscopy (TEM). The bacteria were imaged under a laser scanning confocal microscope. We evaluated the antibacterial efficacy of TPIP-FONs in vitro using sugar plate test. The antimicrobial mechanism was explored by SEM. The biocompatibility of the nanoparticles was examined using cytotoxicity ...

Surface filamentous structures designated pili, and implicated in virulence, have been found on the surfaces of several Gram-positive pathogens. This work describes the conditional expression of two phenotypically distinct pilus-like structures, designated PilA and PilB, on the surface of a hospital-adapted Enterococcus faecium bloodstream isolate. E. faecium is an emerging Gram-positive opportunistic pathogen that can cause severe disease, particularly in immunocompromised patients. Expression of PilA- and PilB-type pili was analysed during different phases of growth in broth culture. During growth, PilA and PilB pilin subunits were expressed around the cross-wall in early-exponential-phase cells. Polymerization and migration of short PilB-type pili towards the poles occurred in cells from the exponential phase and long polymerized pili were expressed at the poles of cells grown to stationary phase. In contrast, PilA-type pili were not expressed in broth culture, but only when cells were grown on solid

The effects of Enterococcus faecium on growth, intestinal barrier function, and immune response in Escherichia coli O78-challenged broiler chickens were investigated. Three hundred eight 1-day-old Ross male chickens were randomly assigned into three treatment groups: negative control (C), E. coli O78-infected positive (EP), and E. coli O78-infected with 200 mg/kg E. faecium dietary supplementation (EF). E. faecium significantly increased the body weight on day 10 (P , 0.05) and day 15. Furthermore, these birds had a greater average daily gain compared with the other groups during days 1-10 (P , 0.05). The death rate of the EF chickens dramatically declined. E. faecium supplementation improved the jejunal villus height and the ratio of villus height to crypt depth (P , 0.05) 3 and 7 days post-infection. The mRNA expression of claudin-1 significantly increased by E. faecium (P , 0.05) 3 and 7 days post-infection, and Mucin2 was markedly enhanced (P , 0.05) 3 days post-infection. E. faecium ...
Food supplements containing viable bacteria, so called probiotics, have been suggested to have beneficial health effects due to their influence on the normal microflora. However, there has been safety concern regarding probiotics containing Enterococcus faecium. Although part of the normal intestinal microflora in humans, enterococci can cause infections such as urinary tract infections, septicaemia, and endocarditis. Enterococci are also inclined to develop antibiotic resistance and their hardy nature promotes survival and dissemination in the hospital setting. Although the importance of E.faecium as a bloodstream isolate is increasing, little regarding its virulence is known. One virulence trait attributed to E. faecium is the enterococcal surface protein, Esp, encoded by the esp gene. Since enterococci have different roles from the human perspective, such as occurrence in food, as probiotic strains, members of the normal intestinal microflora, and as the cause of nosocomial infections, it is ...

6. Antibiotic resistance issues: However, some strains of E. faecium may be pathogenic and harmful to humans, and can cause bacteraemia, endocarditis, urinary tract and other infections. Moreover, anti-microbial resistance (AMR) to many commonly used antibiotics has been reported, and E. faecium is the leading cause of multi-drug resistant enterococcal infections in humans. It is thought that about 70% of E. faecium strains in US hospitals are resistant to vancomycin and 90% are resistant to ampicillin. E. faecium resistance is acquired by gene transfer systems, such as conjugative and non-conjugative plasmids or transposons. Virulence of E. faecium strains is not well understood, but adhesins, haemolysin, hyaluronidase, aggression substance and gelatinase are putative virulence factors. These virulence genes may be transferred to human endogenous strains present in the gastrointestinal tract, which may contribute to increasing the virulence factors of this genus and endogenous strains.

N2 - Vancomycin-resistant Enterococcus faecium is a leading cause of hospital-acquired infections and outbreaks. Regulatory RNAs (sRNAs) are major players in adaptive responses, including antibiotic resistance. They were extensively studied in gram-negative bacteria, but less information is available for gram-positive pathogens. No sRNAs are described in E. faecium. We sought to identify a set of sRNAs expressed in vancomycin-resistant E. faecium Aus0004 strain to assess their roles in daptomycin response and resistance. Genomic and transcriptomic analyses revealed a set of 61 sRNA candidates, including 10 that were further tested ...

Vancomycin-resistant Enterococcus faecium (VREfm) has emerged as an important global nosocomial pathogen, and this trend is associated with the spread of high-risk clones. Here, we determined the genetic and phenotypic features of 93 VREfm isolates that were obtained from patients in 13 hospitals in Vitória, Espírito Santo, Brazil, during 2012-2013. All the isolates were vancomycin-resistant and harbored the vanA gene. Only 6 (6.5%) of the VREfm isolates showed the ability to form biofilm. The 93 isolates analyzed belong to a single pulsed-field gel electrophoresis lineage and presented six subtypes. MLST genotyping showed that all VREfm belonged to ST412 (the high-risk clone, hospital-adapted). The present study describes the dissemination of ST412 clone in the local hospitals. The clonal spread of these ST412 isolates in the area we analyzed as well as other hospitals in southeastern Brazil supports the importance of identifying and controlling the presence of these microorganisms in health ...

A summary of the sequence analysis of the plasmid Tn1546-like elements and their comparison to the prototype element (designated type I in this study) are shown in Fig. 4. The vanS genes of all of the Chinese isolates were identical to that of the BM4147 strain and had no substitutions. Three specific substitutions within VanS result in low-level teicoplanin resistance, which is frequently found in East Asian VRE isolates (9, 15, 18, 34). The Tn1546-like elements of the 13 isolates were classified into six types based on sequence analysis and were designated type I to type VI (Fig. 4). We have reported two VanA-type VRE (E. faecium) clinical isolates, C264 and I125, which were originally isolated from patients in China (35). The Tn1546-like elements of both strains contained the insertion sequences IS1216V and IS1542 and are classified as type V and type VI, respectively (Fig. 4).. Our group reported the first case of VanA-type Enterococcus faecalis: strain KC122.1, isolated in Japan from ...

The distribution characteristics of vancomycin-resistant enterococci (VRE) and the resistance of enterococcus isolates to various antibiotics were investigated in Yae River, which flows through Miyazaki city, Japan. The prevalence of VRE among specimens collected from the urban river basin using mEI agar was 0.9% (2 of 226 enterococcal isolates). In the 333 enterococcal isolates obtained using mEI agar or vancomycin-supplemented mEI agar, the possession of the vancomycin-resistant genes (vanA, vanB, vanC1, and vanC2/C3) was examined using multiplex PCR analysis. Although VRE possessing vanA and vanB were not detected in any isolates, isolates possessing vanC2/C3 were detected at all sampling sites and on all days. All isolates (101 strains) possessing vanC2/C3 that were obtained on vancomycin-supplemented mEI agar were identified as E. casseliflavus and analyzed for genotypes using pulse-field gel electrophoresis (PFGE) analysis. These E. casseliflavus isolates revealed them to be genetically highly

VRE (Vancomycin-resistant Enterococcus) is an infection caused by the bacteria Enterococcus which has become resistant to treatment with vancomycin, an antibiotic commonly used to treat this type of infection. Enterococcus is a type of bacteria that is normally found in human intestines (gut) and the female genital tract and is also often found in the environment without causing disease. When it becomes resistant to vancomycin, it is then called vancomycin resistant Enterococcus or VRE. VRE can be present in an individual but not cause symptoms, this is often called colonization of the bacteria. Sometimes however, the VRE bacteria can cause a variety of infections in the urinary tract, the bloodstream or in open wounds on the skin. VRE is spread by simple skin to skin contact or by touching surfaces contaminated with the bacteria. Most VRE infections spread this way in hospitals. VRE cannot be spread through the air by coughing or sneezing. People at risk for VRE infections include those who ...
Background: Vancomycin-resistant Enterococcus faecium are difficult nosocomial pathogens to treat. Daptomycin (DAP) is a key front-line bactericidal antibiotic against VRE. Development of DAP resistance during therapy raises concerns about the role of DAP monotherapy in severe enterococcal infections. Limited previous data suggest that ceftaroline (CPT) enhances the in vitro activity of DAP against enterococci. We sought to evaluate the in vivo activity of DAP plus CPT against a DAP-R strain of E. faecium using an experimental infective endocarditis (IE) rat model. Methods: MICs and time-kill assays were performed using standard methods. IE was produced in carotid artery and jugular vein catheterized rats by intracardiac inoculation of 10X the ID90 of E. faecium HOU497. Therapy (3 days, via infusion pump) was begun 24 h after inoculation. Some animals were sacrificed at the time of therapy initiation to evaluate bacterial loads (T=0). Drug regimens included i) CPT, 30 min, 40 mg/kg q8h, ii) DAP, ...
VRE, like many bacteria, can be spread from one person to another through casual contact or through contaminated objects. Most often, VRE infections are spread from the hands of health care workers to a patient in a hospital or other facility such as a nursing home. VRE infections are not usually spread through the air like the common cold or flu virus unless you have VRE pneumonia and are coughing, which is rare.. If you are healthy, your chances of getting a VRE infection are very low. Even if you have been exposed to VRE, or have VRE in your body, you are not likely to get an infection. VRE infections typically only occur among people who have weakened immune systems, such as people who have long-term illnesses or people who have had major surgery or other medical procedures and have been treated with multiple antibiotics.. Experts do not know exactly why some people become infected with VRE and others do not. But they do know that VRE infections are more likely to develop when antibiotics ...

Hospital-acquired infections caused by enterococci have increased dramatically since the 1970s. Many nosocomial enterococcal bloodstream infections are associated with medical devices such as central venous catheters. The ability to form biofilm on medical devices is a potential virulence trait that may allow enterococci to cause infections in the expanding population of patients managed with such devices. In this study, the hypothesis that increased ability to form biofilm in vitro is associated with medical-device-related infection in vivo was tested. A microplate assay was employed to assess biofilm-forming characteristics of enterococci in 0.9 % (w/v) sodium chloride, an oligotrophic environment, and BHI, a nutrient-rich environment. Results were compared in isolates from different sources of infection. One hundred and nine enterococcal bloodstream isolates were assayed. Biofilm formation on microplates was demonstrated by all Enterococcus faecalis isolates and 16/38 (42 %) Enterococcus faecium

Background Vancomycin-resistant enterococci (VRE), mostly Enterococcus faecium, are multidrug-resistant microorganisms that can cause nosocomial infections. VRE has increased throughout many European countries, but data from Switzerland are scarce. Aim The aim of this work was to characterise the epidemiology of enterococcal bacteraemias in Switzerland with a focus on VRE. Methods In this observational study, we retrospectively investigated bacteraemias from 81 healthcare institutions from January 2013 to December 2018 using data from the Swiss Centre for Antibiotic Resistance. Only the first blood isolate with E. faecalis or E. faecium from an individual patient was considered. We analysed the annual incidences of enterococcal bacteraemias and determined the proportion of VRE over time. We also assessed epidemiological factors potentially associated with VRE bacteraemia. Results We identified 5,369 enterococcal bacteraemias, of which 3,196 (59.5%) were due to E. faecalis and 2,173 (40.5%) to E. faecium

Bacteria can survive antibiotic treatment both by acquiring antibiotic resistance genes and through mechanisms of tolerance that are based on phenotypic changes and the formation of metabolically inactive cells. Here, we report an Enterococcus faecalis strain (E. faecalis UM001B) that was isolated from a cystic fibrosis patient and had no increase in resistance but extremely high-level tolerance to ampicillin, vancomycin, and tetracycline. Specifically, the percentages of cells that survived 3.5-h antibiotic treatment (at 100 μg · ml−1) were 25.4% ± 4.3% and 51.9% ± 4.0% for ampicillin and tetracycline, respectively; vancomycin did not exhibit any significant killing. Consistent with the changes in antibiotic susceptibility, UM001B was found to have reduced penetration of ampicillin and vancomycin and accumulation of tetracycline compared to the reference strain ATCC 29212. Based on whole-genome sequencing, four amino acid substitutions were identified in one of the tetracycline efflux ...
Enterococcus faecalis biofilm traits and distribution characteristics in China have not been clarified. This study aimed to determine the prevalence and characteristics of E. faecalis biofilm formation in a sample of clinical isolates and to explore the virulence factors associated with biofilm formation in those isolates. A total of 265 E. faecalis isolates were collected from patients in Shenzhen, China. Virulence genes were detected within the genomes of the microbes by polymerase chain reaction (PCR). The isolates were subjected to multilocus sequence typing (MLST) based on housekeeping genes. Biofilms were detected by crystal violet staining. The expression levels of the clinical E. faecalis isolates genes were determined by quantitative real-time polymerase chain reaction. The prevalence of biofilm formation among E. faecalis clinical isolates was 47.2%. MLST yielded 44 different sequence types (STs). The main STs were ST16 and ST179; the ST16 isolates were more likely to form strong or medium

Y1 - 1999/11. N2 - Enterococcus faecalis aggregation substance (AS) mediates efficient bacterium-bacterium contact to facilitate plasmid exchange as part of a bacterial sex pheromone system. We have previously determined that AS promotes direct, opsonin-independent binding of E. faecalis to human neutrophils (PMNs) via complement receptor type 3 and other receptors on the PMN surface. We have now examined the functional consequences of this bacterium-host cell interaction. AS-bearing E. faecalis was phagocytosed and internalized by PMNs, as determined by deconvolution fluorescence microscopy. However, these bacteria ...

Enterococci are gram-positive bacteria that are normal inhabitants of the alimentary tract of humans and other animals. They have been recognized as a cause of infective endocarditis for more than a century (17) and have gained prominence over the last two decades as being among the most common pathogens found in hospital-acquired infections, including urinary tract infections, bloodstream infections, and surgical-site infections (27). The increasing importance of enterococci as nosocomial pathogens can be attributed in part to intrinsic and acquired antibiotic resistance (17, 26). Treatment of multidrug-resistant enterococcal infections poses a significant challenge to clinicians (4, 8), and the potential of these organisms to serve as a reservoir for antibiotic resistance genes is of great concern (6, 20, 21). Despite increasing recognition of the clinical importance of enterococcal infections, their pathogenic mechanisms are not well understood (11).. We have recently developed a novel model ...
Repetitive sequence-based polymerase chain reaction fingerprinting was used to characterize 23 vancomycin-nonsusceptible enterococcal isolates from 2003 to 2004. Five genetically related clusters spanned geographically distinct referring centers. DNA fingerprinting showed infant-to-infant transmission from referring institutions. Thus, community healthcare facilities are a source of vancomycin-nonsusceptible enterococci and should be targeted for increased infection control efforts ...

In this study we have identified a cluster of six genes in E. faecium that are potentially involved in regulation, virulence, and antibiotic resistance and are linked to the esp virulence gene. We have designated this gene cluster a putative PAI because of (i) the Southern blot analysis of esp positive and -negative E. faecium isolates, which demonstrated the presence or absence of the entire gene cluster and a physical link among the seven putative genes in this cluster; (ii) the deviant GC content of this gene cluster (34.4%) compared to the GC content of the E. faecium strain DO chromosome (37.8%); (iii) the presence of putative virulence genes; and (iv) the fact that this island is absent in all human surveillance and animal isolates but present in epidemic and clinical isolates. The large variation in GC content of the seven ORFs present in the putative PAI, ranging from 27.9 up to 43.6%, suggests that this island was generated not as a result of one single event but as a result of a ...
This report published in Communicable Diseases Intelligence Volume 22, No 11, 29 October 1998 contains information on enterococci with acquired resistance to vancomycin and other glycopeptides, which has emerged and spread rapidly through Europe and the United States since 1988.

Supplementary Table 3 and section TraH is an essential component in pIP501-mediated conjugation. Although the paper didnt use the Enterococcus faecalis strain EnGen0234, the Protein Data Bank accession code mentioned in the paper matches the UniProt ID for the EnGen strain. The GO term is appropriate because a mutant strain with a deletion of the traH gene did not conjugate at a level that could be detected by the assay used. However, when the same strain received a plasmid containing a functional copy of the gene, conjugation proceeded at a normal rate.,, ...
