dc.descriptionTo evaluate the antibacterial effect in vitro of the ethanolic extract of Culcitium canescens "vira vira" against Staphylococcus aureus ATCC 25923. Material and methods: experimental in vitro study, for which a strain of Staphylococcus aureus ATCC 25923 was used and 5 groups were considered (16 repetitions each): 2 control groups: nothing was applied to one group and vancomycin was applied to another group; and 3 experimental groups: ethanolic extract of Culcitium canescens (vira vira) at 25, 50 and 100%. Results: the in vitro antibacterial effect of the ethanolic extract of Culcitium canescens on Staphylococcus aureus ATCC 25923 was demonstrated, with three concentrations 25%, 50% and 100%. Based on the results obtained during the investigation, the inhibition halos at the concentrations of 100% and 50% had a mean of 15.94 mm and 9.13 mm respectively, compared to the Duraffourd scale Staphylococcus aureus ATCC 25923 had a medium sensitivity for this. concentration while the inhibition halos obtained with the 25% concentration had a mean of 7.25 mm compared to the Duraffourd scale, this is null. Conclusion: The ethanolic extract of Culcitium canescens presented antibacterial effect against Staphylococcus aureus ATCC 25923 at concentrations of 50% and 100%.es_PE

Material y métodos: estudio experimental in vitro, para lo cual se empleó cepa de Staphylococcus aureus ATCC 25923 y se consideraron 5 grupos (16 repeticiones cada uno): 2 grupos de control: a un grupo no se le aplicó nada y a otro grupo se le aplicó vancomicina; y 3 grupos experimentales: extracto etanólico de Culcitium canescens (vira vira) al 25, 50 y 100%. Resultados: se demostró el efecto antibacteriano in vitro del extracto etanólico de Culcitium canescens sobre Staphylococcus aureus ATCC 25923, con tres concentraciones 25%, 50% y 100%. En base a los resultados obtenidos durante la investigación, los halos de inhibición a las concentraciones de 100% y 50% tuvieron una media de 15.94 mm y 9.13 mm respectivamente, comparado con la escala de Duraffourd Staphylococcus aureus ATCC 25923 tuvo una sensibilidad media para esta concentración mientras que los halos de inhibición obtenidos con la concentración de 25% tuvieron una media de 7.25 mm comparado con la escala de Duraffourd esta es nula. Conclusión: El extracto etanólico de Culcitium canescens presentó efecto antibacteriano frente a Staphylococcus aureus ATCC 25923 a concentraciones de 50% y 100%.es_PE
