2. Enterococcus gallinarum carrying the vanA gene cluster: first report in Brazil
In 2000, Enterococcus faecalis resistant to vancomycin was first reported at a tertiary hospital in Porto Alegre, southern Brazil. The resistance spread to other hospitals and surveillance programs were established by hospital infection committees to prevent the spread of vancomycin-resistant enterococci. In February 2002, an isolate initially identified at

3. Molecular characterization of the VanA element in enterococci with incongruent genotype and phenotypes relative to glycopeptide resistance. / Caracterização molecular de elementos VanA em enterococos com genótico e fenótipo discrepantes relativos à resistência aos glicopeptídeos
Enterococos resistentes aos glicopeptídeos representam, atualmente, importantes patógenos causadores de infecção nosocomial, sendo isolados em várias regiões do mundo, inclusive no Brasil. Dos fenótipos de resistência descritos até o momento, VanA e VanB são os mais encontrados. O fenótipo VanA é caracterizado por linhagens resistentes a altos n�

5. Vancomycin-Resistant Enterococci from Humans and Retail Chickens in Taiwan with Unique VanB Phenotype-vanA Genotype Incongruence
Vancomycin resistant enterococci (VRE) with VanB phenotype-vanA genotype incongruence were found in all 39 VRE isolated from chicken carcasses and four human VRE isolates in Taiwan. Three identical mutations in the vanS gene were found in the VanB phenotype-vanA genotype VRE sequenced. This finding indicates possible transmission of glycopeptide resistance a

6. Molecular epidemiology and antibiotic susceptibility of enterococci in Cincinnati, Ohio: a prospective citywide survey.
To determine patterns of antimicrobial susceptibility among enterococci and to assess molecular characteristics of vancomycin-resistant enterococci, 157 clinical blood isolates of enterococci from 10 hospitals in Cincinnati, Ohio, were prospectively collected during a 6-month period from February to July 1995. The isolates included 108 (69%) E. faecalis isol

7. Emergence of Vancomycin-Resistant Enterococci in Australia: Phenotypic and Genotypic Characteristics of Isolates
Enterococci with resistance to glycopeptides have recently emerged in Australia. We developed multiplex PCR assays for vanA, vanB, vanC1, and vanC2 or vanC3 in order to examine the genetic basis for vancomycin resistance in Australian isolates of vancomycin-resistant Enterococcus faecium and E. faecalis (VRE). The predominant genotype from human clinical E.

8. Selection of a Teicoplanin-Resistant Enterococcus faecium Mutant during an Outbreak Caused by Vancomycin-Resistant Enterococci with the VanB Phenotype
Vancomycin-resistant enterococci (VRE) have recently become an increasing problem in hospitals in Poland, being responsible for a growing number of nosocomial outbreaks. In this work, we have analyzed the second outbreak of VRE with the VanB phenotype to be identified in the country. It was caused by clonal dissemination of a single strain of vancomycin-resi

9. Outbreak of Vancomycin-Resistant Enterococcus faecium of the Phenotype VanB in a Hospital in Warsaw, Poland: Probable Transmission of the Resistance Determinants into an Endemic Vancomycin-Susceptible Strain
The first outbreak caused by vancomycin-resistant enterococci of the VanB phenotype in Poland was analyzed. It occurred in a single ward of a Warsaw hospital which is a specialized center for the treatment of hematological disorders. Between July 1999 and February 2000, 11 patients in the ward were found to be infected and/or colonized by Enterococcus faeciu

10. Vancomycin-Resistant Enterococcus faecium Strain Carrying the vanB2 Gene Variant in a Polish Hospital
About 2.5 years after the first isolation of the VanA phenotype of vancomycin-resistant Enterococcus faecium (VREM) in Poland, the first VREM strains with the VanB phenotype have emerged independently in two different Warsaw hospitals. In one of these the VREM strain was selected during the long-term antimicrobial treatment of a patient with a wide variety o

11. Emergence of vanA Genotype Vancomycin-Resistant Enterococci with Low or Moderate Levels of Teicoplanin Resistance in Korea
In Korea, vancomycin-resistant enterococci have become important nosocomial pathogens since the late 1990s, and most vancomycin-resistant enterococcal isolates have been VanA phenotype-vanA genotype strains. In 2001, we experienced an outbreak of VanB phenotype-vanA genotype vancomycin-resistant enterococci at a university hospital. This is the first report

12. Rapid characterization schemes for surveillance isolates of vancomycin-resistant enterococci.
Surveillance cultures for vancomycin-resistant enterococci (VRE) and subsequent characterization of the isolates can be extremely burdensome and difficult. Therefore, efficient and reliable schemes for the characterization of surveillance isolates are needed. In this study, a commercial agar (bile esculin azide agar with 6 microg of vancomycin per ml [BEAA];
