Crystal Diagnostics Successfully Detects
Deadly Ebola Virus in Less Than 20 Minutes
PRWEB, July 09, 2015
Rapid Ebola detection indicates that the CDx platform technology is well suited for Medical Device Applications.
Crystal Diagnostics (CDx) has successfully detected live Ebola virus with its unique liquid crystal-based rapid pathogen detection system. Those tests were conducted at the University of Texas Galveston Medical Branch Biosafety Level 4 (BSL-4) facilities. Tests demonstrated detection at variable concentrations of live Ebola Zaire in serum samples in less than 20 minutes.
The CDx Xpress System combines proprietary liquid crystal technology with highly specific antibody-coated paramagnetic microspheres to selectively capture and detect Ebola virus faster than other commercial systems.
CDx sells rapid pathogen systems in the Food Safety market to quickly and accurately detect food borne pathogens in a variety of products including meat and produce. The company’s systems are in use in commercial test labs, government agencies, universities, and research facilities, as well as food processors. The Ebola detection project is the first application outside of the food safety arena for CDx. Continue reading…
Liquid Crystal-Based Detection System
Revolutionizes Food Pathogen Testing in Terms of
Speed and Accuracy
By Curtis H. Stumpf, Ph.D., 23-Mar-2015
Over the last 20 years, little has changed in food pathogen testing with detection systems primarily based on culture, molecular (nucleic acids) or antibody (mostly lateral flow) systems. Although these systems have had years of field testing for performance upgrades and optimization, the basic concepts and problems of these systems remain the same. Since 2006, Crystal Diagnostics has been working to revolutionize pathogen detection through development of a liquid crystal-based pathogen detection system, a more rapid and accurate system using the selectivity of antibody capture and the signal amplification of liquid crystal. The result is the first liquid crystal-based biosensor, the Crystal Diagnostics Xpress Detection System.
Crystal Diagnostics (CDx) was created in 2006 out of a research collaboration between scientists at the Northeast Ohio Medical University and Kent State University (KSU). KSU is home to the world renowned Liquid Crystal Institute and birthplace of the first liquid crystal display. Over the last 8 years of research and development, Crystal Diagnostics and its partners have secured 15 patents, and entered the commercial market with its first detection platform in 2013.
The detection technology uses highly selective antibody-based capture paired with sensitive amplification by a liquid crystal matrix to detect pathogens in complex food types. After sample enrichment, antibodies bound to microspheres are utilized to selectively harvest pathogenic bacteria if present in the sample. When captured pathogens are bound to antibody-coated microspheres, immune complexes are formed. These immune complexes are then loaded into a proprietary BioCassette, cooled to allow alignment of the liquid crystal, and detected within 10 minutes using the high resolution optics of the Xpress Detection System.

Crystal Diagnostics Awarded AOAC-PTM Accreditation for the Rapid Detection of “Big-6” E. coli Food Pathogens
January 20, 2015; Boulder, CO/Rootstown, OH
Unprecedented speed and accuracy for detection of STECs adulterants is now part of the CDx product line
Crystal Diagnostics (CDx) Xpress System, a rapid and sensitive detection platform, announced today that it has received AOAC-PTM Certifications for the six non-O157 Shiga toxin-producing E. coli (serogroups O26, O45, O1O3, O111, O121, and O145; collectively referred to as STEC or the “Big-6”) as well asE. coli O157, at 1 colony forming unit (cfu) per 325g of raw ground beef and raw beef trim, or 200g of raw spinach.
The CDx Xpress System combines proprietary liquid crystal technology with antibody-coated paramagnetic microspheres to selectively capture and detect STEC from food matrixes, faster than other commercial systems.
The USDA requires all federally inspected beef processors to test for these potentially deadly pathogens and Crystal Diagnostics becomes one of only seven companies to gain AOAC accreditation. Continue reading…
The U.S. Department of Agriculture is considering
expanded STEC testing to include ground beef
By News Desk, 19-Nov-2014
The U.S. Department of Agriculture is considering whether or not to expand its non-O157 Shiga toxin-producing E. coli (STEC) testing to include ground beef and ground beef components beyond beef manufacturing trimmings.
This week, USDA’s Food Safety and Inspection Service (FSIS) posted its analysis of estimated costs and benefits associated with implementing the additional testing.
Testing of beef manufacturing trimmings currently costs about $1.37 million each year and adding in raw ground beef, bench trim and other components would add $1 million.
The $2.37 million total would break down into $1.38 million is for FSIS and just under one million for the industry.

The USDA Food Safety Inspection Service (FSIS) is maintaining its position on the implementation of its Salmonella Action Plan
By Michael Fielding, 26-Jun-2014
USDA’s Food Safety and Inspection Service (FSIS) is maintaining its position on the implementation of its Salmonella Action Plan, in light of Wednesday’s introduction of legislation that would give the agency the authority to recall any product contaminated with salmonella and campylobacter.
On Wednessday, Congresswomen Rosa DeLauro (D-Conn.) and Louise Slaughter (D-N.Y.) introduced the bill, essentially forcing the issue nearly one month after a consumer health advocacy group filed a lawsuit alleging inaction by the USDA on a petition to declare antibiotic-resistant salmonella as an adulterant.
“We appreciate the Congresswomen’s ongoing efforts on our shared goal of ensuring food safety standards continue to be stringent, effective, and constantly improving,” according to an emailed statement to Meatingplace by an FSIS spokesperson. “FSIS will continue to work aggressively in preventing foodborne illness, including implementing the first ever performance standards for Salmonella in chicken parts and ground poultry later this year.”
The Salmonella Action Plan, released in December 2013, outlines several actions FSIS will take to drive innovations that will lower Salmonella contamination rates, including establishing new performance standards and developing new strategies for inspection and throughout the full farm-to-table continuum.
