RESUMEN
RESUMEN La resistencia a antibióticos es un problema mundial importante. El objetivo de este estudio fue determinar la resistencia a los antibióticos en cepas comensales aisladas de niños sanos de comunidades rurales de Moyobamba y Urubamba en Perú. Este estudio de cohorte identificó 179 cepas de Escherichia coli comensales provenientes de 93 niños, seguidos durante seis meses. Trece antibióticos fueron analizados mediante disco difusión. Los mayores índices de resistencia fueron para cotrimoxazol (49,1%), ampicilina (48,0%) y ácido nalidíxico (31,8%). Se encontró un aumento en la resistencia del 11,6% para el ácido nalidíxico y del 6,4% para el cotrimoxazol en este periodo. El 34,0% de los aislados fueron multidrogoresistentes. Este estudio respalda hallazgos previos de resistencia a múltiples fármacos en cepas comensales en comunidades rurales, y destaca el aumento en las tasas de resistencia en el tiempo. Recomendamos estudios en poblaciones más grandes, con un seguimiento más prolongado.
ABSTRACT
ABSTRACT Antibiotic resistance is a major global problem. The objective of this study was to determine antibiotic resistance in commensal strains isolated from healthy children from rural communities of Moyobamba and Urubamba in Peru. This cohort study identified 179 commensal E. coli strains from 93 children, followed for six months. Thirteen antibiotics were analyzed by diffusion disk. The highest rates of resistance were for cotrimoxazole (49.1%), ampicillin (48.0%), and nalidixic acid (31.8%). An 11.6% increase in resistance was found for nalidixic acid and 6.4% for cotrimoxazole in this period; while 34.0% of the isolates were multidrug-resistant. This study supports previous findings of multidrug resistance in commensal strains in rural communities and highlights the increased rates of resistance over time. We recommend studies in larger populations with a longer follow-up.
