Definition Causes and symptoms Diagnosis Treatment Prognosis Prevention Resources |
The occurrence of diarrhea in an individual while traveling is very suggestive of TD. Although there are other possible causes, these are less likely. In most instances, the specific organism responsible for the symptoms does not need to be identified, and the majority of patients need only rest and treatment to avoid potential complications.
When patients develop fever or bloody diarrhea, the illness is more serious and a specific diagnosis is needed. In those cases, or when symptoms last longer than expected, stool samples are obtained to identify the organism.
For this purpose, laboratories can either try to grow (culture) the organism, or identify it with high-powered micro-scopes (electron microscopy) or with the use of special tests or stains. These can show parasites such as Giardia, Amoeba, Cryptosporidium and others in freshly obtained stool specimens. New techniques that involve identification of DNA (the characteristic material that controls reproduction and is unique for all individuals) of the various organisms, can also be used in special circumstances.
