Mixed enteric infection.

long chronic diarrhoea may be due to Campylobacter jejuni: we were unable to determine any other aetiology and the patient responded to selective treatment for Campylobacter and never relapsed. Campylobacter enteritis is usually a self-limiting illness. Symptoms resolve in less than 10 days, even without antibiotic therapy. Sometimes one needs two or three weeks to be cured. We have found only seven well documented cases in which the duration ofdiarrhoea exceeded 3 weeks from 2 months to 20 months.'-5 In our patient the duration was 17 years. It is the longest chronic diarrhoea due to Campylobacter jejuni that we know about.
