Background: Vancomycin (glycopeptide)-resistant enterococci (VRE or GRE) can cause serious problems for hospitalized patients due to the limited options for treatment of VRE infections. As infection with VRE increases in hospitals, further knowledge about vancomycin resistant genes is needed. Methods: Isolates of Enterococcus spp. were collected from hospitalized patients in Tehran (Iran) durin...
We examined cloacal samples from poultry raised on nonintensive production farms in Brazil for the presence of vancomycin-resistant enterococci. No VanA- or VanB-containing enterococci were identified in a total of 200 cloacal swabs. The most prevalent species were Enterococcus gallinarum (vanC1; 13.0%) and E. casseliflavus (vanC2/3; 5.5%).
We compared PCR to conventional culture for the detection of vancomycin-resistant enterococci (VRE) in 30,835 rectal samples over a 3-year period. The positive and negative predictive values of vanB PCR were 1.42% and 99.9%, respectively. A positive vanB result by PCR is poorly predictive and necessitates culture for differentiation of VRE-positive and -negative individuals.
The vanM gene was first found in a vancomycin-resistant Enterococcus faecium (VREm) isolate in Shanghai in 2006. In this study, we found that, in 70 VREm strains isolated in nine Shanghai hospitals from 2006 to 2014, vanM was more prevalent than the vanA gene (64.3% [45/70] versus 35.7% [25/70]). The vanM-type isolates showed similar antimicrobial susceptibility patterns with the vanA types. Th...
Vancomycin-resistant Enterococcus faecium has emerged as a multidrug-resistant pathogen in hospital settings. Here, we present the draft genome sequence of a high-level vancomycin-resistant strain, E. faecium ATCC 51559, which is employed as a standard laboratory vanA genotype-positive control strain for clinical and laboratory studies.
Hospitals in the United States are under increasing pressure to perform active surveillance cultures for detection of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) among newly admitted patients. Results of such cultures can then be used to direct contact precautions to prevent transmission of MRSA and VRE in the health care setting. However, using...
Oritavancin is in the final stages of clinical development for treatment of acute bacterial skin and skin structure infections. This drug has demonstrated potent activity against staphylococci (minimum inhibitory concentration [MIC] for which 90% of isolates are inhibited [MIC(90)], 0.06 μg/mL), enterococci (MIC(90), ≤ 0.008 to 0.5 μg/mL), and streptococci (MIC(90), ≤ 0.008 to 0.12 μg/mL), incl...
