Reiter's syndrome in association with enteritis due to Campylobacter fetus ssp. jejuni

An 18-year-old girl with Reiter's syndrome after febrile diarrhoea was found to be infected with Campylobacter fetus spp. jejuni. Excretion of campylobacter into stools was stopped by erythromycin therapy, but active polyarthritis lasted for 6 months. The patient was positive for HLA B27.
