Travellers' diarrhoea caused by Campylobacter jejuni.

Over a period of 18 months Campylobacter jejuni was isolated from the faeces of 19 (5.8%) of 329 travellers with diarrhoea, among 2488 patients attending the Outpatient Department of Tropical Diseases at Aurora Hospital. Incidences of Salmonella, Shigella and C. jejuni in diarrhoeal patients were very similar. C. jejuni caused initial symptoms of diarrhoeal disease indistinguishable from travellers' diarrhoea from other causes. Double bacterial or bacterial-parasitic infections were shown in 22 patients. During the same period at Aurora Hospital a total of 48 patients were found to have imported C. jejuni from 21 countries outside Scandinavia. Of these 83% had been on tourist trips.
