Natural compounds from marine algae namely flavonoids may play a role in the remedy of this condition. \nAim: \nThis research aims to assess the potency of flavonoids extracted from Enteromorpha intestinalis and Caulerpa prolifera as antibacterial agents. \nMethods: \nE. intestinalis was collected from Western Libyan Coast and C. prolifera was collected from Farwa Island. The antimicrobial activity and determination of minimum inhibitory concentration of algal flavonoid containing extracts was performed in vitro against some positive and negative Gram bacteria.\nResults: \nCrude extract containing flavonoids from E. intestinalis were more effective than C. prolifera extract against Staphylococcus aureus with antimicrobial essay (25-28+1 and 14.5-37.5+0.5-1.5), MIC (50 and 50-250 \u00b5g\/mL), MBC (75 and 75-250 \u00b5g\/mL). In Bacillus cereus, the antimicrobial assay (19-24.5+0.5-1.5: 24+1), MIC (50-250 + 100 \u00b5g\/mL) and MBC (250 and 125 \u00b5g\/mL). On the other hand, flavonoids containing extract from C. prolifera were more effective than E. intestinalis against Enterohemorrhagic Escherichia coli O157   EHEC O157 (25-28+1: 14-18.5+0.5-1.5), MIC (100-250:100-500 \u00b5g\/mL) and MBC (150-250 and 250-500 \u00b5g\/mL). Salmonella enterica qualitatively combat by flavonoid from E. intestinalis (13.5-14+0.5-1: 10.5-13.5+0.5-1.5), MIC (100-250: 250 \u00b5g\/mL) and MBC (100-250: 250 \u00b5g\/mL). Flavonoids from C. prolifera (4 strains: 2 strains) were effective against S. enterica. Crude flavonoids from both algae were not effective against Bacillus pumilus. \nConclusion: \nData from this study could conclude that flavonoid extracts from E. intestinalis and C. prolifera could be used against foodborne bacterial agents.<\/jats:p>","DOI":"10.5455\/ovj.2024.v14.i3.3","type":"journal-article","created":{"date-parts":[[2024,4,13]],"date-time":"2024-04-13T12:27:16Z","timestamp":1713011236000},"page":"769","source":"Crossref","is-referenced-by-count":4,"title":["Antibacterial activity of flavonoid extracts from Enteromorpha intestinalis and Caulerpa prolifera against multidrug resistant foodborne bacterial isolates"],"prefix":"10.5455","volume":"14","author":[{"given":"Rabia","family":"Alghazeer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salah","family":"Azwai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdalla","family":"Elmansori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid","family":"Alzintani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sana","family":"Elghmasi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asma","family":"Alnajjar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ftaim","family":"Gammoudi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maamar","family":"Sidati","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samia","family":"Hawisa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aboubaker","family":"Garbaj","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Eldaghayes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Open Veterinary Journal"],"original-title":[],"link":[{"URL":"https:\/\/ejmanager.com\/mnstemps\/100\/100-1691239750.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:16:54Z","timestamp":1791483414000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ejmanager.com\/mnstemps\/100\/100-1691239750.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2024]]}},"URL":"https:\/\/doi.org\/10.5455\/ovj.2024.v14.i3.3","relation":{},"ISSN":["2226-4485"],"issn-type":[{"value":"2226-4485","type":"print"}],"subject":[],"published":{"date-parts":[[2024]]}}}
