Antibiotic resistance in Bacteria is one of the emerging health related problem in the world nowadays. Plants and among them algae are valuable natural sources effective against infectious agents. Methanolic extracts of fourmarine algae ofAlgeria coastwere investigated for antibacterial activity against six pathogenic bacteria (Bacillus subtilis, Listeria innocua, Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa). Susceptibility assays using disc diffusion and broth microdilution test for the determination of minimum inhibitory concentration (MIC) were employed to asses the antibacterial activity of methanolic extracts of algae.All algae extracts showed antibacterial activity against four of the six pathogenic bacteria tested with MIC values ranged between 0.25-3mg/ml. Extract of Rhodomela confervoïdes exhibited the highest activity against Bacillus subtilis (24 mm). Cystoseira tamariscifolia exhibited the highest activity against Listeria innocua (19.67mm)
