[Enteropathogenic microorganisms in children with acute diarrhea in 2 hospitals of Rosario, Argentina].

As part of a multicenter collaborative study the relative frequency of enteropathogenic agents in children less than 5 years of age with acute diarrhea was determined. Rates of isolation were similar as regards sex, age, and season. The frequency of polymorphonuclear cells (PMN) in the stools was significantly higher among patients requiring admission in comparison with ambulatory patients.
