In vitro susceptibilities of 4,208 enterococci (83% Enterococcus faecalis isolates, 13.6% Enterococcus faecium isolates, and 3.4% isolates of other species) from patients in 27 European countries towards 16 antibiotics were determined. High-level resistance to gentamicin varied by country (range, 1 to 49%; mean, 22.6% +/- 12. 3%) and per species (19.7% E. faecalis isolates, 13.6% E. faecium iso...

the main objective of this study was to investigate the effect of enterococci isolated from traditional lighvan cheese on the quality of iranian uf white during ripening. four samples of cheese were provided from four different cheese production units in lighvan region. strains of enterococci in these samples were isolated by standard microbiological methods and selective medium of kanamycin es...

INTRODUCTION Vancomycin-resistant enterococci (VRE) among haemodialysis patients has increased rapidly and, to date, there is no report of this incidence in Portugal. METHODS A total of 121 faecal samples were collected from haemodialysis patients, and then tested for VRE. Antimicrobial resistance, virulence and multilocus sequence typing (MLST) were studied. RESULTS VRE prevalence was 3.3%...

Enterococcus species were considered as non-pathogenic bacteria until recognized as an important cause of bacterial endocarditis in 1899. During the past decade, there has been a worldwide increase in occurrence of enterococcal infections. Though more than 28 enteroccocal species described, Enterococcus faecalis and Enterococcus faecium are isolated most frequently. This might be explained by t...

Enterococci are Gram-positive facultative anaerobic bacteria commonly found in the gastrointestinal tract of the mammals and birds. These cocci are isolated from urinary tract infections, bacteremia, endocarditis, and burn wounds in humans. The evolution of antibiotic-resistant enterococci raised a problem due to the possibility of the transmission of these organisms between poultry and human. ...

From 125 separate cloacal cultures from three turkey flocks fed virginiamycin, 104 Enterococcus faecium and 186 Enterococcus faecalis isolates were obtained. As the turkeys aged, there was a higher percentage of quinupristin-dalfopristin-resistant E. faecium isolates, with isolates from the oldest flock being 100% resistant. There were no vancomycin-resistant enterococci. Results of pulsed-fiel...

Enterococci are increasingly recognized as an important nosocomial pathogen. The present study was done to establish the changing paradigm of blood culture enterococcal isolates and emergence of Enterococcus faecium as a nosocomial pathogen. A total of 150 Enterococcal isolates were obtained during the study period from January 2013 to March 2014. 68.3% and 31.7% of adult and 53% and 43% of pae...

Enterococci are Gram-positive bacteria that are found in plants, soil and as commensals of the gastrointestinal tract of humans, mammals, and insects. Despite their commensal nature, they have also become globally important nosocomial pathogens. Within the genus Enterococcus, Enterococcus faecium, and Enterococcus faecalis are clinically most relevant. In this review, we will discuss how E. fae...

In this study the distribution of species and antimicrobial resistance among vancomycin resistant enterococci (VRE) recovered from clinical specimens obtained from five hospitals in Belgrade was analyzed. Strains were further characterized by pulsed-field gel electrophoresis (PFGE). Polymerase chain reaction (PCR) was used to investigate the presence of vanA and vanB genes and pathogenicity fac...

BACKGROUND Enterococci are indigenous flora of the gastro-intestinal tracts of animals and humans. Recently, interest in two major species, E. faecium and E. faecalis, has heightened because of their ability to cause serious infections and their intrinsic resistance to antimicrobials. This study was aimed at determining the prevalence of E. faecium and E. faecalis in human faecal samples and ev...
