title: [Bacterial isolation in infants hospitalized for acute diarrhea].
abstract: Bacteria were investigated in stools of 156 children under two years of age admitted to the pediatric wards of a general hospital at the western metropolitan area of Santiago, Chile, because of acute diarrhea with only one stool sample. A known pathogenic agent was isolated from 115 cases (73.7%), this being a bacteria in 87/115 (75.6%). Most prevalent microorganisms were Enteropathogenic Escherichia coli (EPEC). (65.5%), specially serogroups 0111, 0119 and 055, Enterotoxigenic Escherichia coli (ETEC) (18.4%), Campylobacter yeyuni (13.8%), Salmonellae (9.2%) and Shigellae (6.9%). Invasive Escherichia coli (EIEC) and Aeromonas hydrophila were observed in only one case. Yersinia enterocolitica was not isolated. Age was under one year in 92% of patients and 83% were normally or slightly under nourished. Fecal leucocytes were abnormally increased (greater than 5 per high power field) in 41.4% of positive bacterial isolates, in 83% of children with Shigellae, in 50% of those with EPEC and Salmonellae and in 25% of the Campylobacter yeyuni group.
