How to send an isolate?

It must be guaranteed that your isolates arrive in optimal condition for testing and that the packaging complies with national and international regulations.

The NRCs regularly receive isolates that are needlessly destroyed or made unsuitable for testing
because of poor packaging.

Each isolate must be accompanied by a submission/epidemiological form. Preferably isolate the submission form from the samples in a waterproof bag. Each data (patient information, specimen source, symptoms, sporadic case/outbreak, traveling history, serotype) is recorded for detection of epidemiological trends and outbreaks at an early stage.



Analyses submission forms:

  • Salmonella/Shigella submission form [fr] [nl]
  • Neisseria meningitidis submission form [fr] [nl]
  • Listeria submission form [fr] [nl]
  •  Mycobacteria submission form [fr] [nl]

Where do I get my results?

For Shigella and human Salmonella you can get your test results online, see the following page.

How do I order an analysis?

The analysis order form is available for download : analysis_order_form.pdf
Fill it and send it back to us jointly with the isolate, we will get back to you.



List of National Reference Centers

Belgian reference laboratories (in French or Dutch), responsible for laboratory diagnostic testing for specific organisms, for confirmatory testing of samples from other laboratories or for subtyping of isolates antibiotic resistance testing. The role of the National Reference Centers in the network of Sentinel laboratories [French] [Dutch]


Human Salmonella, Listeria, Shigella and Neisseria meningitidis isolates are transferred on a voluntary basis to the respective National Reference Centre (NRC) for serotyping by clinical microbiology laboratories. Salmonella and Listeria strains from meat and meat products, isolated as part of the official monitoring program of the Belgian Food Agency (FASFC) are also transferred to the NRC, but on a mandatory basis
The serotyping is performed according to internationally recognized standards. Serotyping of Salmonella and Shigella is accredited in accordance with the requirements of the ISO 17025 standard.
Phage typing of Salmonella is performed on isolates according to the recommendations of the Health Protection Agency (Colindale, UK) by the NRC for Phage Typing.
