UNLABELLED Enterococcus faecium has recently emerged as an important multiresistant nosocomial pathogen. Defining population structure in this species is required to provide insight into the existence, distribution, and dynamics of specific multiresistant or pathogenic lineages in particular environments, like the hospital. Here, we probe the population structure of E. faecium using Bayesian-ba...
A virulent bacteriophage (Ec-ZZ2) that infects Enterococcus faecium was isolated from sewage. The bacteriophage belongs to the family Siphoviridae and has a linear double-stranded DNA genome, with a length of 41,170 bp and a 34.59% G+C content, which is highly similar to Enterococcus phage IME-EF4.
A nucleotide transversion from guanine to uracil in the 23S rRNA confers linezolid resistance. We describe a real-time PCR using two Taqman probes that detects a single mutated allele among the genomes of Enterococcus faecium and Enterococcus faecalis. Results were confirmed by a classical approach involving LabChip technology assayed with an Agilent Bioanalyzer 2100.
Enterococcus faecium strain 10/96A (VanD4) was the first vancomycin-resistant enterococcus (VRE) isolated in Brazil. Subsequent Brazilian VRE strains have all had the VanA phenotype. Multilocus sequence typing showed that strain 10/96A was isolated sporadically, has a unique sequence type (ST 281), and was not the progenitor of the VRE strains isolated from hospital outbreaks in Brazil.
Neonatal bacterial sepsis is one of the major causes of morbidity and mortality in neonates. 10% cases of neonatal bacteraemia and septicaemia are caused by Enterococci. The increasing incidence of Vancomycin resistant enterococci (VRE) is of particular concern because of limited treatment options and increased mortality. We report here a case of neonatal sepsis in a premature baby caused by va...
We compared ChromID VRE and Brilliance VRE media for the detection of vancomycin-resistant enterococci (VRE). Using a panel of 28 enterococcal isolates, 10 vanA Enterococcus faecium and three vanA Enterococcus faecalis isolates grew as per manufacturers' instructions whilst growth of two vanC and eight vancomycin-susceptible enterococci was inhibited on both media. Important differences were no...
Enterococci are a major cause of health care-associated infections and account for approximately 10% of all bacteremias globally. The aim of this study was to determine the proportion of enterococcal bacteremia isolates in Australia that are antimicrobial resistant, with particular emphasis on susceptibility to ampicillin and the glycopeptides, and to characterize the molecular epidemiology of ...
Enterococcus faecalis and Enterococcus faecium are among the leading causes of hospital-acquired infections. Reliable and quick identification of E. faecalis and E. faecium is important for accurate treatment and understanding their role in the pathogenesis of infections. Fluorescent in situ hybridization (FISH) of whole bacterial cells with oligonucleotides targeted at the 16S rRNA molecule le...
Enterococci are intrinsically resistant to numerous antimicrobial agents. We examined the energy-dependent efflux of radiolabeled drugs from four reference strains of Enterococcus faecalis and a strain of Enterococcus faecium and found that most strains pumped out norfloxacin and chloramphenicol. Efflux of tetracycline was detected only in certain strains.
