Genotypic (molecular) methods are usefull to identify bacteria, fungi and viruses in food or environmental matrix as a complement or alternative to phenotypic methods. Their rapidity is crucial to develop effective preventive and/or adjustment measures. Besides sensitivity and specificity enhancement of the detection process, they also reduce much of the subjectivity inherent to interpreting morphological and biological data. They are becoming the key method for rapid and reliable detection.
Another key advantage of molecular methods is the identification of virulence factors of pathogenic bacteria. Virulence factors are gene products that enable a microorganism to establish itself on or within a host of a particular species and enhance its potential to cause disease.
Molecular methods have also revolutionized food-borne pathogenic virus detection by providing new tools to detect viruses like noroviruses (the single most common cause of gastroenteritis), hepatitis A virus (the majority of adults remain susceptible with risk of large outbreak) or rotaviruses in various food products.
By its close relations with the National Reference Laboratory in Microbiology and the Laboratory of Foodstuffs microbiology (LMDA, Liege University, Vet Faculty), DNAVision AgriFood has a strong background in molecular detection of pathogenic foodborne bacteria and viruses.
In the frame of a strong collaboration with the molecular microbiologists of the Microbiology LMDA, DNAVision AgriFood has already developed a comprehensive portfolio of genetic services to identify :
By regularly answering specific demands, DNAVision has also developed a straightforward methodology and organisation to optimise and validate new tests for urgent customer demands with an incomparable speed and reliability. Thanks to this reliable methodology, DNAVision AgriFood has already answered quickly to specific demands from industrials or public organisations.
DNAVision has already processed samples from environmental, biotechnology, healthcare and food industries.
Our current portfolio includes molecular detection of many species like:
Bacillus cereus |
Listeria monocytogenes |
Vibrio cholerae |

Through its subcontracting laboratory, DNAVision AgriFood has been the first european laboratory to propose the first test ISO 17025 accredited for the detection of Hepatite A and Noroviruses in seafruits.
DNA extraction from other food matrices is developed by DNAVision. For more information, please contact us at: info@dnavision.be
DNAVision scientists have already been involved in several validations of molecular methods for microorganisms diagnostic. These validations were carried on according to ISO 16140 guidelines under a quality assurance system (ISO 17025 compliant environment) with a careful and detailled documentation and archival of all the results for the homologation process. Those unique and high-quality services were carried on within publicly granted R&D projects or through contract service for privately held companies.
