title: [Epidemiological aspects of enteritis due to Campylobacter jejuni].
abstract: From September 1986 through July 1987, all fecal specimens obtained from infants and children who visited the pediatric clinic of the Shizuoka General Hospital with complaints of abdominal pain or diarrhea were examined for thermophilic Campylobacters. Bacteriological and epidemiological studies were performed on household contacts. The mothers of the patients were compared with the mothers of age-matched control subjects. Bacteriological examination of animals in 49 primary schools in Shizuoka city was performed. C. jejuni was isolated from 47 (9.4%) of the 499 feces samples, occupying first place in the bacterial etiology of acute bacterial enteritis. Infants and young children below 10 years of age comprised 81% of the total cases. Fourteen (13%) strains of C. jejuni were isolated in 9 families among 105 household contacts of the index patients. Six symptomatic contacts in two households had eaten the same suspected chicken as the respective index patients. In three families, C. jejuni was isolated from the remainder of the chicken. The serotype of these isolates was identical to that of the isolates from the index cases and the other family members. It was also noted that the same chopping boards were used for the preparation of salads after cleansing with water. In two index cases, the antibody of convalescent serum against C. jejuni isolated from the chicken, as estimated by passive hemagglutination method, ranged from 1:320 to 1:1280. These facts strongly supported the assumption that they had been infected by the chicken. The remaining persons were asymptomatic and the possibility was left that the index cases had been secondarily infected by these carrier persons.(ABSTRACT TRUNCATED AT 250 WORDS)
