Agentes patógenos en el síndrome diarreico agudo no enterocólico

Abstract

Along a one year period 112 infants admitted with non enterocolic acute diarrhea were studied for isolation of potentially ethiologic agents, namely enteropathogenic bacteria (Salmonella, Shigella, Campylobacter, classic enteropathogenic, enteroinvasive and enterotoxigenic Escherichia coli), Rotavirus (viral RNA electrophoresis) and enteroparasites (Telemann and PAFS). The most frequently identified pathogen was rotavirus (57.8%), followed by thermo labile toxin producing Escherichia coli (19.7%). The frequency of classic enteropathogenic Escherichia coli was 13.9%, that of thermo stable toxin producing Escherichia coli 5.7%, Shigella 4.1%, Campylobacter 3.3% and Salmonella 1.6%. Bacteriae were isolated from 40.2%, of patients, predominantly in summer. Enteroparasites were detected in 13.1% of the cases, Entamoeba histolytica being the most frequent. In 32.8% of the cases more than one pathogen was isolated.
