[Surveillance study on bacteriological etiology of 8371 children with diarrhea].

The results of stool cultures from 8371 children of 0-13 years old with diarrhea during the years of January 1981 to December 1989 in Shanghai area are reported. 2906 strains of enteropathogenic bacteria were isolated, with total detection rate of 34.72%. Shigella were still the most common pathogens in 1981-1984, and Campylobacter jejuni took second place, whereas from 1985 on Campylobacter exceeded Shigella as the first pathogenic bacteria of children's diarrhea. Except in 1987 and 1988 Shigella sounei predominated over Shigella flexneri in detection rate within the past nine years, the detection rates of EPEC and Salmonella were lower. It was significant that Salmonella typhimurium was about half the number for Salmonella non typhi. During 1986 and 1987 we specially isolated and identified Vibrionaceae bacteria with 130 strains of Vibironaceae detected, occupying third place among pathogens of children's diarrhea in these two years, and among which aeromonas were the most common. This article analyses in detail the distribution of enteropathogenic bacteria with respect to their species, genus and serum type.
