|Description||Gastroenteritis causes significant morbidity. The laboratory routinely cultures for Campylobacter, Salmonella, Shigella species and E. coli O157. It is important to include a travel history and important details such as "watery diarrhoea" on the request so that we can decide to look for other enteric pathogens that are not routinely cultured..|
|Indication|| Samples submitted on patients who have been in hospital longer than 3 days will only be tested for C.difficile|
|Additional Info||If E.coli 0157 or typhoid is strongly suspected or if the patient has any of the following clinical details; HUS, PUO, history of travel with fever, then requests should clearly be marked "Danger of Infection"|
|Concurrent Tests||Rotavirus testing by enzyme immunoassay (EIA) will automatically be carried out on all samples submitted on patientís under 5 years of age
Cryptosporidium and Giardia testing by EIA will automatically carried out on patients with a travel history, appropriate clinical details and liquid stool samples.|
|Collection Conditions|| Collect specimens as soon as possible after onset of symptoms and where possible before antimicrobial therapy.
Shigella species may not survive the pH changes that occur in stool specimens which are not promptly delivered to the laboratory even if refrigerated.
For Rotavirus, peak viral counts occur on days 3-5 after onset of symptoms.
If processing is delayed, refrigeration is preferable to storage at ambient temperature.|
