We compared ChromID VRE medium with Enterococcosel containing vancomycin for the detection of vancomycin-resistant Enterococcus in 1, specimens. The new chromogenic agar chromID VRE (cIDVRE; bioMérieux) was compared with bile esculin agar (BD) containing 6 mg/liter vancomycin for the detection of. The performance of the recently developed Seeplex VRE detection kit was compared with chromID VRE agar and the conventional blood agar plate with.

Although Gram-negative bacilli species not identified were the major source of false-positive results by the chromID VRE agar, this problem was resolved by Gram staining. The primers cromid a wide range of annealing temperatures and provide high specificity [ 5 ]. Clin Microbiol Infect ; Google Scholar Articles by Lee, S.

Selective isolation of vancomycin-resistant enterococci. Open chfomid a separate window. Surg Infect ; 9: Resistance mechanism and epidemiology of vancomycin-resistant enterococci. The comparison of our results with those of other studies is difficult since in most of the latter direct plating was used without enrichment methods.

In addition, the difference in specificity may be associated with differences in the enrichment broth, such as the concentration of chromud and supplementary use of other antibiotics.

The same sensitivity was found in our laboratory for VCA3 agar 5. Rapid detection of vanA and vanB genes directly from clinical specimens and enrichment broths by real-time multiplex PCR assay. J Clin Microbiol ; However, no consensus has been established for medium base, vancomycin concentration, or method of use. In this window In a new window. In addition, the prevalence of vancomycin-resistant Enterococcus species other than E.


First nosocomial outbreak of vancomycin-resistant Enterococcus faecium expressing a VanD-like phenotype associated with a vanA genotype. Data Summary, January through June Vancomycin-resistant enterococci VRE are among the most important nosocomial pathogens [ 1 ]. Guidelines for the control of glycopeptide-resistant enterococci in hospitals. Outbreak of colonization and infection with vancomycin-resistant Enterococcus faecium in a French university hospital.

They were processed the same way as in the initial study. Infection with VRE leaves clinicians with few or no treatment options. Hospital outbreak of vancomycin-resistant enterococci caused chromjd a single clone of Enterococcus raffinosus and several clones of Enterococcus faecium. In Korea, these organisms have been reported with increasing frequency as the use of oral vancomycin has increased since [ 2 ].

To reduce the turn-around-time, evaluation is needed of its performance without use of enrichment broth. From November to Februarya total of 1, rectal swab specimens were collected from intensive care units for detection of VRE.

Vancomycin and teicoplanin MICs were determined by E-test for resistant strains. The large number of samples investigated during this study and the low prevalence of VRE provided the opportunity to explore the false positives. Cre genotypic testing be done on all phenotypically vancomycin-resistant cnromid detected in hospitals? Development of a standardized screening cnromid for detection of vancomycin-resistant enterococci. Of them, 37 were identified as VREfm; the other 2 isolates were Pediococcus pentosaceus and an unidentified Gram-positive coccus.

ChromID VRE in combination with Gram straining provided a higher specificity than Enterococcosel, irrespective of the incubation time and enrichment. Skip to main content. Search for related content. Evaluation of a rapid enrichment-PCR method for the detection of vanA vancomycin-resistant enterococci in fecal specimens. Evaluation of a new chromogenic medium, ChromID VRE, for detection of vancomycin-resistant enterococci in stool samples and rectal swabs.


VREs were detected by all three methods in 28 specimens.

Recommendations for preventing the spread of vancomycin resistance. VanA- or vanB -carrying E. In Europe, a high prevalence has also been observed cgromid the United Kingdom VRE can transfer vancomycin resistance to other Gram positive cocci, especially Staphylococci [ 3 ], and are multi-drug resistant with limited therapeutic options [ 4 ].

Comparison of direct plating and broth enrichment culture for the detection of intestinal colonization by glycopeptide-resistant enterococci among hospitalized patients. Although the enrichment step is not chrmoid performed, we included it because PCR and chromID VRE agar-based culture combined with enrichment in EB showed high sensitivity without loss of specificity [ 689 ].

Because some vancomycin-resistant Enterococcus species other than E.

In an ver study in Septemberrectal swab specimens from patients admitted to intensive care units were screened for presence of VRE. Glycopeptide-acquired resistance has emerged in Enterococcus faecalis and Enterococcus faeciumwhich are designated vancomycin-resistant Enterococcus species VRE.
