RESUMO

Four hundred and ninety acute diarrheical episodes where studied during a period of one year, corresponding to 445 children that were examined, most of them as out-patients at the "Centro de Saúde Escola de Paulinia" and at the "Pronto Socorro" of the "Hospital Municipal de Paulinia". The clinical and epidemiological data from each patient were written on specific charts. Stools samples were taken on 288 episodes, from 282 children. The following enteropathogenic agents were seek: rotavirus, adenovirus, ETEC, EPEC, Shigella sp, Salmonella sp, Yersinia sp, Campylobacter sp, Giardia lamblia, Entamoeba histolytica, and Cryptosporidium spp. Positive identification occurred in 59,4% of the episodes, the Bacterial were the most frequent, followed by enteropathogenic viruses agents and finally enteroparasites. Bacterial agents were commonly seen in summer and the viral in the colder months of the year. The most frequent agent found was the rotavirus, that is among 13,5% of the episodes. The second agent in frequency was the E.coli enterotoxigenic, identified in 12,1% of the samples. Among the phenotypes studied, the commonest strains found belong to LT-only producers. None of the colonization factors studied, such as CFA/I, CFA/II and CFA/IV was detected in this research. E. coli enteropathogenic was identified in 7,0% and Giardia lamblia of the episodes. Shigella sp was identified in 5,2% of the samples and the strains of S.sonnei were more frequent than S.f1exneri. E. histolytica was identified in 2,0% of the episodes and adenovirus in 1,0%. EIEC and Cryptosporidium spp occurred in 0,7% and 0,3% of the cases. Campylobacter sp, Salmonella sp and Yersinia sp were not detected among the samples examined. E. coli enterotoxigenic and Shigella sp occurred more in children over 12 months old. This research showed some differences from most of the other studies carried out in Brazil, like the priority of ETEC among the bacteria, less occurrence of EPEC and Salmonella sp and greater frequency of S. sonnei over S. flexneri
