Resumen
El presente estudio se realizó en el Hospital General Jipijapa durante el período agosto – octubre 2012 con el objetivo de establecer la presencia de bacterias patógenas de la familia Enterobacteriaceae en muestras de pacientes pediátricos con diagnóstico presuntivo de gastroenteritis. Las muestras de 50 niños de 6 meses hasta los 12 años que cumplieron criterios de inclusión fueron analizadas mediante coprocultivo. Se detectó que de las cepas recuperadas, 66% pertenecieron a Enterobacteriaceae, con el predomino de Salmonella spp (54,55%) seguida por Escherichia coli (39.39%), aisladas de las muestras de pacientes menores de 5 años. Dos cepas de Shigella (6.06%) fueron recuperadas de muestras de niños del grupo etario desde 5 hasta 12 años. Todas cepas de Salmonella spp probadas frente fosfomicina, ceftriazone, cefotaxima, ceftazidima, ampicilina+sulbactam, chlorafenicol y ciprofloxacina mostraron sensibilidad, mientras que hacia otros antibióticos se registró presencia de resistencia: para ampicilina se detectó 50.00%, ácido nalidixico – 44.44%, sulfatrimetropin, tetraciclina y gentamicina – 27.78%. El 84.62% de las cepas de Escherichia coli aisladas presentan resistencia a ampicilina, 53.85% a tetraciclina, 30.77% a gentamicina y 23.08% a amoxicilina + ácido clavulanico; 2 cepas de Shigella spp mostraron resistencia frente ampicilina, ácido nalidixico, tetraciclina. chlorafenicol, ampicilina+sulbactam y cefotaxima y amoxicilina + ácido clavulamico.

This study was conducted in the Jipijapa Hospital during the August – October 2012 in order to establish the presence of pathology bacteria of the family Enterobacteriaceae in samples of pediatric patients with presumptive diagnosis of gastroenteritis. Samples of 50 children aged 6 months to 12 years who met inclusion criteria were analyzed by stool culture. I detected that strains recovered , 66% belonged to Enterobacteriaceae, with the prevalence of Salmonella spp. (54,55%) followed by Eschirichia coli (39,39%). Isolated from samples of children age group from 5 to 12 years. All Salmonella strain tested against fosfomycin, ceftriazone, cefotaxime, ceftazidime, ampicillin + sulbactam, and ciprofloxacin showed chlorafenicol sensitivity, while other antibiotics were recorded presence of resistanced. 50,00% to ampicillin, nalidixie acid 44,44%, sulfatrimetropin, tetracycline and gentamicin 27,78% was detected. The 84,62% of strains of Escherichie coli isolates are resistant to ampicillin, tetracycline 53.85%, 30,77% to 23,08% to gentamicin and amoxicillin + clavulanic acid; 2 Shigella spp. strains showed resistanced against ampicillin, nalidixic acid, tetracycline, chlorofenicol, sulbactam and ampicillin, cefotaxime + clavulanic acid and amoxicillin.
