Negative plates should be re-incubated for an additional 24 hours. The medium should be allowed to warm to room temperature before inoculation. Techniqueīrilliance CRE Agar can be inoculated direct from rectal screening swabs, faecal samples or from an isolated colony prepared as a liquid suspension, approximately equivalent to 0.5 McFarland turbidity, according to local guidelines. Accuracy minimizes costs by ensure that only those in need receive what can be costly treatment. This allows a rapid response from infection control teams and enables the patient to receive the most appropriate treatment, as early as possible. Plates are incubated at 37✬ and provide high sensitivity and specificity, with results available in just 18–24 hours. The novel background makes the white or naturally pigmented colonies of non-CRE organisms, like Acinetobacter, easy to spot, all of which means you can screen for CRE direct from patient samples in just 18 hours. Acinetobacter, may grow, but they produce white or naturally pigmented colonies which are easy to spot against the novel turquoise background. Other carbapenem-resistant organisms not from the Enterobacteriaceae family, e.g. coli (pale pink) from the KESC group organisms, which grow blue. The two-chromogen system differentiates E. The formulation contains a modified carbapenem at a level recommended by both EUCAST and CLSI, ensuring reliable results with a wide variety of carbapenem-resistant organisms, including New Delhi Mettalo β-lactamase -1 (NDM-1). Also, these are confirmation tests and not suitable for patient screening, since primary culture must be conducted first.Īs the number of CRE being isolated has increased, especially in geographies, such as India, Greece, Israel, Turkey and New York in the U.S.A., so had the need for an accurate, easy-to-use screening method to help identify colonized patient more quickly.īrilliance CRE Agar makes detecting CRE-colonized patients easy. However, MHT is technically demanding, and the results are often subjective and open to interpretation, so is no longer recommended by the CLSI or EUCAST. Traditionally, CRE detection has relied on antimicrobial susceptibility testing in conjunction with synergistic methods, like the Modified Hodge Test (MHT). Early detection of carbapenem-resistant Enterobacteriaceae (CRE) will allow faster implementation of appropriate strategies to treat patients and limit the spread of these pathogens. However, the rapid emergence and dissemination of Enterobacteriaceae resistant to carbapenems poses a considerable threat to clinical patient care and public health 2. coli and the Klebsiella, Enterobacter, Serratia and Citrobacter (KESC) group, direct from clinical samples, in 18 hours.Ĭarbapenems (imipenem, meropenem, ertapenem and doripenem) are invaluable for the treatment of multi-resistant Gram-negative bacterial infections, including producers of extended spectrum β- lactamases (ESBL) 1. * Adjusted as required to meet performance standards Descriptionīrilliance™ CRE Agar provides presumptive chromogenic identification of carbapenem-resistant E. Brilliance CRE Agar is not FDA cleared for sale in the US. Please speak to your local Oxoid supplier. Brilliance™ CRE Agar is a chromogenic screening plate for the detection of carbapenem-resistant Enterobacteriaceae.
