Campylobacter jejuni/coli is recognized as a common bacterial cause of enteritis. Many workers have reported that Campylobacter enteritis is a disease as common as Salmonellosis. On the other hand, it has been reported that the incidence of symptomless excreters is less than 1% in industrialized countries. The numbers which have been tested by almost all workers were too small to be able to achieve statiscal significans of the sex, age and other incidence, though. We studied the frequency of incidence of C. jejuni/coliin stools of healthy people. During the period from July 1980 to May 1982, 836 healthy persons were tested for 1-9 times, once every two months, basically. But, positive persons were tested at the next month also, so a total of 3385 stools were tested. C. jejuni/coli was isolated from 41 out of 3357 fecal specimens (isolation rate was 1.22%). The frequency of isolation rates were 0.62-2.19 during a year. The isolation rate in winter (2.19%) was significantly higher than in summer (0.62%) and autumn (0.62%) (p< 0.05). It was not clear whether or not the isolation rates were different. The frequency of isolation rate is more or less equal between sexes (male 0.82%, female 1.25%). Teen agers had significantly higher isolation rates (4.17%) than the elder age groups (0.64-1.50%) (p< 0.05). It may be derived that Campylobacter enteritis is more frequent in children. C. jejuni/coli in stools had disappeared till one or two months after the first isolation.
