RESUMO
Out of 45558 patients admited in our hospital, from January 1990 to December 1993, the clinical records of 4445 children with diarrhoea (4289 with acute diarrihoea and 156 with persistent diarrhoea) were reviewed. Those with positive bacteriological or parasitological results were taken as sample. Salmonella was the bacteria most frequently isolated in both groups of patients. ECEP and ECEH had a similar distribution while Shigella showed a higher frequency in cases of persistent diarrhoea, for a third pace of incidence. From the parasitological point of view, Cryptosporidium and Giardia had the same behavior.

The etiology and pathogenesis of persistent diarrhoea is usually multifactorial and sometimes can not be identified. It is necessary to define if an alteration of the enteric microflora is a risk factor that influence the duration of the diarrhoea. 30 infants with acute diarrhoea and 30 with persistent diarrhoea were studied. A sample of duodenal content was taken by a double-lumen tube and processed microbiologically in search for enteric microorganisms, anaerobic and Candida. These results were correlated with the nutritional status, the previous use of Metronidazole and the results of the stool culture. The presence of bacterial overgrowth and the identification of the duodenal microflora is an important factor for the persistence of the diarrhoea. There was a quantitative and qualitative alteration of the duodenal flora in both groups of patients.
