The new CarbDetect AS-2 Kit
(item number 247100096)
- The rapid and global emergence of carbapenemase-producing organisms (CPO) is an alarming threat to patient safety and healthcare systems.
- CPOs are resistant to all beta-lactam antibiotics and they are usually also resistant against other classes of antibiotics.
- CPOs are most conspicuous in hospitals and frequently cause nosocomial infections. However, they can asymptomatically colonize healthy carriers and this might play a major role in their global spread.
- Traditional phenotypic tests are generally time consuming and need well trained lab personal. Furthermore, most tests do not allow a detailed molecular identification of the actual carbapenemase gene that is needed for epidemiological and infection control purposes.
- Therefore, molecular methods are required for a rapid and reliable identification of carbapenemase genes.
- This could be solved by combining all relevant targets to date in a single test using a multiplex microarray-based assay for detection and identification.
- Starting from a clonal CPO culture, the microarray-based CarbDetect AS-2 assay detects and differentiates nearly all carbapenemase genes within 8h (Hand-on Time 2h) (e.g., blaKPC, blaNDM, blaVIM, blaOXA-48).
- Other relevant ESBL and NSBL genes can also be identified (e.g., blaCTX-M1, blaCTX-M9, blaOXA-1) as well as additional genes associated with aminoglycoside, quinolone, macrolide, sulfonamide and trimethoprim resistance (e.g., aac(6â€™), mph, qnr, sul, dfr).
- The CarbDetect AS-2 assay identifies the genes from a given carbapenem resistant strain which phenotypic methods alone cannot provide.
- The CarbDetect AS-2 assay provides information which help to prevent and trace outbreaks.
- The CarbDetect AS-2 assay delivers the best molecular tool for monitoring and control of CPOs.
- multiplex approach which replaces several single- and multiplex PCRs that could detect only the most common carbapenemase genes
- identification of rare carbapenemase genes
- identification of ESBL and NSBL genes
- identification of other relevant antibiotic resistance genes
- identification of the most prevalent pathogens (Escherichia coli, EIEC, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Citrobacter freundii, Shigella spp., Salmonella spp. and Enterobacter spp.)
- accurate detection of patients colonized with CPOs will help to prevent outbreaks and determine the best infection prevention pathways

Please send either a clonal culture (e.g., suitable agar plate, stab culture or swab) or a high quality DNA preparation into our lab. We do the genotyping and you get a result file in electronic form. On request, we will perform a phenotypical characterization of antibiotic susceptibility and/or species identification by a VITEK-2 System (bioMÃ©rieux Deutschland GmbH).
Alere Technologies provides customised manufacturing of microarrays mounted in ArrayTube, ArrayTube2 and/or ArrayStrip. You decide which markers/genes you focus on. It is possible to adapt the existing assays/gene lists according to your requirements!
