In order to investigate the applications of mangrove forests in Vietnam, nine mangrove plants including <em>Kandelia obovata</em>,<em> </em><em>Pluchea</em><em> pteropoda </em>Hemsl.,<em> </em><em>Aegiceras</em><em> corniculatum </em>(L.) Blanco,<em> </em><em>Lumnitzera</em><em> racemosa </em>Wild.,<em> </em><em>Sonneratia </em><em>caseolaris </em>(L.) Engl.,<em> </em><em>Sonneratia </em><em>apetala </em>Buch. Ham,<em> </em><em>Bruguiera </em><em>gymnorrhiza </em>(L.) Lam,<em> </em><em>Rhizophora </em><em>stylosa </em>Griff.<em> </em>and<em> </em><em>Avicennia</em><em> marina </em>(Forsk.) Vierh. were collected in Xuan Thuy National Park, Nam Dinh province, Vietnam. Methanol extracts from barks and leaves of these species were used to evaluate antibacterial activity against 4 control bacteria <em>Escherichia coli </em>ATCC®25922<em>™*</em>;<em> Staphylococcus aureus </em>ATCC®25923<em>™</em>;<em> Proteus mirabilis </em>ATCC®29245™ and<em> Proteus vulgaris </em>ATCC®33420™ <em>via</em> the agar well diffusion method. All of methanol extracts from nine mangrove plant species collected in Xuan Thuy National Park inhibited the growth of tested pathogenic bacterial strains. <em>Lumnitzera</em><em> racemosa </em>Wild., <em>Sonneratia</em><em> caseolaris </em>(L.) Engl. and <em>Sonneratia </em><em>apetala </em>Buch. Ham expressed the highest antibacterial activity. <em>Aegiceras corniculatum </em>(L.) Blanco and <em>Avicennia </em><em>marina </em>(Forsk.) Vierh showed medium activity. <em>Kandelia obovata</em>, <em>Pluchea </em><em>pteropoda </em>Hemsl., <em>Rhizophora</em><em> stylosa </em>Griff. and <em>Bruguiera</em><em> gymnorrhiza </em>(L.) Lam showed the lowest activity.</p> ER -
