dc.description.abstractThe antibacterial activity of ethanol, methanol, hexane and acetone-based extracts of the macroalgae Padina gymnospora (PG), Hypnea musciformes (HM), Ulva fasciata (UF) and Caulerpa prolifera (CP) was investigated. The disk diffusion method was used to evaluate the algae antimicrobial effect against standard strains of Vibrio parahaemolyticus, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella enterica and five virulent antibiotic-resistant strains of V. brasiliensis, V. xuii and V. navarrensis (isolated from the hemolymph of Litopenaeus vannamei). Ethanol extracts of PG and HM inhibited all Vibrio strains. E. coli and P. aeruginosa were only susceptible to ethanol extracts of PG. Among the methanol extracts, only UF was bioactive, inhibiting V. navarrensis. The observed inhibitory effect of ethanol extracts of PG, HM and UF against virulent antibiotic-resistant bacteria suggests these macroalgal species constitute a potential source of bioactive compoundspt_BR

dc.description.abstract-esSe investigó la actividad antibacteriana de los extractos de etanol, metanol, hexano y acetona de las macroalgas Padina gymnospora (PG), Hypnea musciformes (HM), Ulva fasciata (UF) y Caulerpa prolifera (CP). Se utilizó el método de difusión en disco para evaluar el efecto antimicrobiano de las algas contra cepas patrón de Vibrio parahaemolyticus, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa y Salmonella enterica y cinco cepas virulentas y resistentes a los antimicrobianos: V. brasiliensis, V. xuii y V. navarrensis (aislado de la hemolinfa de Litopenaeus vannamei). Los extractos de etanol de PG y HM inhibieron todas las cepas de Vibrio. E. coli y P. aeruginosa solo eran susceptibles a los extractos de etanol de PG. Entre los extractos de metanol, solo UF fue bioactivo, inhibiendo V. navarrensis. El efecto antibacteriano de los extractos de etanol de PG, HM y UF contra bacterias virulentas y resistentes a los antimicrobianos sugiere que estas especies de macroalgas constituyen una fuente potencial de compuestos bioactivos.pt_BR
