Gastrointestinal infections due to consumption of contaminated seafood/shellfish or water are most commonly associated with, V.parahaemolyticus, V.vulnificus and , V.alginolyticus. Travel associated infection with V.cholerae can lead to severe illness (cholera) which may quickly become fatal if untreated.

Vibrio Species DNA
Vibrio bacteria are pathogens which are found in water. There are a number of species which cause infection although cases are rare in Ireland.
Non-cholera bacteria such as V.parahaemolyticus, V.vulnificus, V.fluvialis can lead to several clinical manifestations which are generally mild and self-limiting. Symptoms include diarrhoea, abdominal pain and fever.
Infection due to V.cholera is characterised by profuse watery diarrhoea resulting in dehydration with fluid and electrolyte loss and is associated with a poor outcome.
The incubation period for Vibrio-associated diseases ranges from less 1 day to several days. An individual may be infectious for up to 14 days after contracting a Vibrio infection.

In addition to the packaging of samples, the transport/delivery of clinical samples to the laboratory is required to be in adherence to all national regulations for the safe transport of biological materials. Enfer Medical provides a fully compliant logistics service, aligned with clients’ testing requirements.
Prompt transport of specimens:
To ensure prompt testing of samples and release of results within the published test turnaround times, samples should arrive to the laboratory by 18:00. Test turnaround time is measured from receipt of the sample at the laboratory until the time the authorised results are reported to users.
In rare cases specimens may not be suitable for testing on arrival to the laboratory. In that case the sample will be rejected at the receipt stage and the service user will be notified immediately and an explanation as to why the sample could not be processed will be provided. Reasons why samples cannot be processed include but are not limited to:
- Samples received beyond the stability limits and/or not at the correct temperature indicated for each test.
- Incorrect sample type received.
- Leaking samples, sample not received or sample insufficient for analysis as stated below within sample requirements.
- Non-compliant samples or request forms i.e. those missing sample date information, missing sample test request and/or missing sample site/type information.
- Samples received without the necessary patient identifiers.
- NOT DETECTED
