dc.description.abstractEl objetivo de la presente investigación fue determinar la actividad antimicrobiana de las diferentes concentraciones del extracto hidroalcohólico de hojas de Piper angustifolium “matico” sobre el crecimiento de Proteus mirabilis en condiciones de laboratorio. Para la obtención del extracto hidroalcohólico de hojas de P. angustifolium se empleó un equipo Soxhlet con alcohol etílico al 95 %, se hicieron diluciones con Tween 80 (10, 15, 20, 25 y 30 mg/ml). Para evaluar la actividad antimicrobiana del extracto se empleó el método Kirby-Bauer con discos de papel Watman N° 4 de 0,7 mm, empleándose cinco discos para cada una de las concentraciones más un control positivo (Ciprofloxacina®) y un control negativo (Tween 80), las placas fueron incubadas a 37°C durante 24 horas, posteriormente fueron medidos los diámetros (mm) de los halos de inhibición. Se obtuvo el mayor halo de inhibición (18,7 mm) a la mayor concentración, encontrando un efecto directamente proporcional entre la concentración del extracto y la actividad antimicrobiana. Los resultados evidenciaron diferencias significativas entre las diferentes concentraciones utilizadas.es_PE
dc.description.abstractThe aim of the present investigation was to determine the antimicrobial activity of different concentrations of hydroalcoholic extract of Piper angustifolium “matico” leaves on the growth of Proteus mirabilis under laboratory conditions. To obtain the hydroalcoholic extract of P. angustifolium leaves, Soxhlet equipment with 95% ethyl alcohol was used; dilutions were made with Tween 80 (10, 15, 20, 25 and 30 mg / ml). To evaluate the microbial activity of the extract, the Kirby-Bauer method with 0.7 mm Watman No. 4 paper discs was used, using five discs for each of the concentration, using ciprofloxacin as a positive control and a negative control (Tween 80), the plates were incubated at 37 ° C for 24 hours, after which time the diameters (mm) of the inhibition zones were measured. The highest inhibition halo (18.7 mm) was obtained at the highest concentration, finding a directly proportional effect between the concentration of the extract and the antimicrobial activity. The results showed significant differences between the different concentrations used.es_PE
