نبذة مختصرة : Materiales y métodos: se aislaron e identificaron enterobacterias de teléfonos celulares mediante cultivos microbiológicos y pruebas bioquímicas. El extracto hidroalcohólico de A. absinthium se obtuvo por extracción Soxhlet. Su actividad antimicrobiana se evaluó mediante el método de Kirby-Bauer, midiendo los halos de inhibición a diferentes concentraciones Resultados: se identificaron enterobacterias como Klebsiella pneumoniae, Enterobacter aerogenes y Proteus mirabilis. El extracto al 50% y 100% mostró inhibición significativa, con halos de hasta 28 mm, mientras que a concentraciones más bajas su efectividad disminuyó Conclusión: el extracto hidroalcohólico de A. absinthium exhibe una notable actividad antimicrobiana frente a enterobacterias aisladas de teléfonos celulares, destacando su potencial como alternativa para la desinfección ; Objective: to evaluate the antimicrobial activity of the hydroalcoholic extract of Artemisia absinthium against enterobacteria isolated from cell phone surfaces at the Bio-Inca pharmacy, Cajamarca Materials and methods: enterobacteria were isolated and identified from cell phones by microbiological cultures and biochemical tests. The hydroalcoholic extract of A. absinthium was obtained by Soxhlet extraction. Its antimicrobial activity was evaluated by the Kirby-Bauer method, measuring the inhibition halos at different concentrations Results: enterobacteria such as Klebsiella pneumoniae, Enterobacter aerogenes and Proteus mirabilis were identified. The 50% and 100% extract showed significant inhibition, with halos of up to 28 mm, while at lower concentrations its effectiveness decreased Conclusion: the hydroalcoholic extract of A. absinthium exhibits a remarkable antimicrobial activity against enterobacteria isolated from cell phones, highlighting its potential as an alternative for disinfection
