Expanded RiboPrinter® System Database from DuPont Qualicon Helps Identify, Track and Trend Bacterial Contamination

The RiboPrinter® microbial characterization system from DuPont Qualicon now includes more than 6,900 RiboPrint™ patterns of interest to the pharmaceutical, food and public health sectors.  The DUP 2008 update, which does not alter the operating software, adds genetic “fingerprints” for over 219 genera and 1,440 species and serotypes of bacteria to the onboard identification database.

The automated RiboPrinter® system uses powerful genetic information to provide a genetic snapshot, or RiboPrint™ pattern, of any bacterium in less than eight hours.  With electronic data security features and characterization below the species level, the RiboPrinter® system surpasses U.S. Food and Drug Association guidelines for systems that identify contamination and help assure consistency in aseptic processing.

“These new patterns make it even easier for customers to pinpoint and characterize contaminating bacteria in their products and operations,” said Kevin Huttman, president -- DuPont Qualicon.  “Each database expansion adds significant value for customers who rely on the RiboPrinter® system to help them monitor trends at their site and track contamination back to its source.”

Along with the RiboPrinter® system, DuPont Qualicon markets the award-winning BAX® detection system, an innovative DNA-based technology for screening food and environmental samples for pathogens or other organisms.  The BAX® detection system provides polymerase chain reaction (PCR) assays to screen food and other samples for Salmonella, Listeria, Listeria monocytogenes, E. coli O157:H7, Enterobacter sakazakii, Campylobacter, Staphylococcus aureus, and yeast and mold.  For more information and photos, please visit
