Vancomycin resistant Enterococcus mechanism

The mechanism of resistance to vancomycin found in enterococcus involves the alteration of the peptidoglycan synthesis pathway. The D-alanyl-D-lactate variation results in the loss of one hydrogen-bonding interaction (four, as opposed to five for D-alanyl-D-alanine) being possible between vancomycin and the peptide First recognized in the mid-1980s, vancomycin-resistant enterococci (VRE) have become an issue of enormous concern over the past decade.27 Only 6 years after the first descriptions of these organisms from clinical specimens, guidelines aimed at controlling the spread of multiply resistant enterococci were promulgated at a national level.16.

Vancomycin-resistant enterococci. After they were first identified in the mid-1980s, vancomycin-resistant enterococci (VRE) spread rapidly and became a major problem in many institutions both in Europe and the United States. Since VRE have intrinsic resistance to most of the commonly used antibiotics and the ability to acquire resis vancomycin-resistant Enterococcus (VRE) (1). However, there is debate about the optimal approach to screening and infection control, which may differ between pathogens of interest. Members of the genus Enterococcus are well-documented pathogensassociatedwithvariousclinicalmanifestations,includ-ingbacteremia,infectiveendocarditis,intra-abdominalandpelvi Infection with vancomycin-resistant Enterococcus is associated with an increased mortality rate, illustrated by a 2.5-fold increase in mortality for patients suffering from VRE bacteremia . Vancomycin resistance in Enterococcus spp. has been increasing in prevalence since it was first encountered in 1986 (6, 7) The main mechanism of glycopeptide resistance (e.g., vancomycin) in enterococci involves the alteration of the peptidoglycan synthesis pathway, specifically the substitution of D-Alanine-D-Alanine (D-Ala-D-Ala), to either D-Alanine-D-Lactate (D-Ala-D-Lac) or D- Alanine-D-Serine (D-Ala-D-Ser). 31, 32 Such alterations can lead to variable expressions of glycopeptide resistance The vanHAX Mechanisms of Vancomycin Resistance Vancomycin resistance in enterococci occurs through a reprogramming of PG formation involving five different genes, two of which (vanR and vanS) are required for inducing the biosynthetic genes vanHAX

  7. Vancomycin resistant Enterococcus was isolated in Europe in the late 1980s. However the use of Vancomycin began clinical use in the 1950s but was not wide spread until 1970s. Vancomycin works by inhibiting cell wall formation in gram positive bacteria and by this mechanism

vancomycin-resistant E. faecalis and E. faecium in England (248). Shortly after the first isolates of vancomycin-resistant enterococci (VRE) were reported by investigators in the United Kingdom and France (155, 248), similar strains were detected in hospitals located in the eastern half of the United States (104). Subsequently, VRE have spread with unantici Vancomycin is an antibiotic that is often used to treat these infections. Antibiotics are medicines that are used to kill bacteria. Enterococcus germs can become resistant to vancomycin and therefore are not killed. These resistant bacteria are called vancomycin-resistant enterococci (VRE) Mechanism of acquired resistance Strains of hVISA and vancomycin-intermediate Staphylococcus aureus (VISA) do not have resistant genes found in Enterococcus and the proposed mechanisms of resistance include the sequential mutations resulting in a thicker cell wall and the synthesis of excess amounts of D-ala-D-ala residues INTRODUCTION. Vancomycin-resistant enterococci (VRE) are a common and difficult-to-treat cause of hospital-acquired infection. The epidemiology of VRE and strategies for preventing its spread will be reviewed here. The infection control measures described are applicable to all resistant enterococci Further, vancomycin-resistant Enterococcus faecalis emits a sex pheromone that promotes plasmid transfer, and it has been recently demonstrated that this same pheromone is produced by S. aureus. Emission of this pheromone by S. aureus organisms that are in proximity to vancomycin-resistant enterococci that contain plasmids encoding van genes could result in transfer of these resistance genes.

Vancomycin-resistant enterococci infections are treated with antibiotics, which are the types of medicines normally used to kill bacteria. VRE infections are more difficult to treat than other infections with enterococci, because fewer antibiotics can kill the bacteria What is a vancomycin resistant enterococcus (VRE)? VRE is a strain of bacteria that can cause infection. Usually the antibiotic vancomycin is used to kill the bacteria. However, VRE is resistant to vancomycin and makes it difficult to treat. VRE most commonly causes an infection in the urinary tract, blood, or a wound THE VIRULENCE AND BIOFILM FORMING MECHANISM OF SELECTED VANCOMYCIN-RESISTANT Enterococcus faecium ABSTRACT Vancomycin-resistant enterococcus (VRE) is an emerging nosocomial pathogen which causes outbreaks in hospitals worldwide. It is, therefore, important to understand the virulence and how this organism persists as a nosocomial pathogen In recent decades, however, some enterococci have become resistant to vancomycin. The two main species that cause problems are vancomycin-resistant Enterococcus faecium and vancomycin-resistant Enterococcus faecalis. E. faecium is the most common species of VRE. These bacteria are not the same genus as other common fecal bacteria such as E. coli Genetic Changes Identified in the Vancomycin-Resistant Enterococcus faecalis Isolate That Was Resistant to Daptomycin (Strain R712) as Compared with the Daptomycin-Susceptible Isolate (Strain S613)
