Campylobacter is the most common cause of food poisoning in the UK.
It has a low infective dose so only a few bacteria (less than 500) can cause illness.
Undercooked meat (especially poultry) is often associated with illness, as is unpasteurised milk and untreated water. Although it does not normally grow in food, it has a low infective dose so only a few bacteria (less than 500) can cause illness.
Campylobacter is also recognised as a frequent cause of ‘traveller diarrhoea.
Treatment is mainly directed at fluid replacement with electrolyte replacement therapies.
In some instance antibiotics may be indicated.
Indications for antimicrobial therapy include high fever, systemic infection with sustained bacteraemia, grossly bloody diarrhoea, and persistence of symptoms for >1 week. Antibiotics should also be used in immunocompromised patients. Antibiotics are not indicated in uncomplicated cases.
