ABSTRACT
Antibacterial effects of aqueous and ethanolic extracts of seeds of moringa (Moringa oleifera) and pods of soursop (Annona muricata) in the concentration of 15 and 110 in volumes 50, 100, 150 and 200 µL were examined against Staphylococcus aureus, Vibrio cholerae, Escherichia coli (isolated from the organism and the aquatic environment) and Salmonella Enteritidis. Antibacterial activity (inhibition halo > 13 mm) against S. aureus, V. cholerae and E. coli isolated from the whiteleg shrimp, Litopenaeus vannmaei, was detected in aqueous and ethanolic extracts of moringa. E. coli isolated from tilapiafish, Oreochromis niloticus, was sensitive to the ethanolic extract of moringa. The aqueous extracts of soursop showed an antibacterial effect against S. aureus and V. cholerae, but the antibacterial activity by the ethanol extracts of this plant was not demonstrated.
RESUMO
Para avaliação do efeito bactericida frente à Staphylococcus aureus, Vibrio cholerae, Escherichia coli (isolada de pescados e ambiente aquático) e Salmonella Enteretidis, foram testados extratos aquosos e etanólicos de sementes de moringa (Moringa oleifera) e casca de graviola (Annona muricata) na concentração de 15 e 110, nos volumes de 50, 100, 150 e 200 µL. Os resultados mostraram efeito antibacteriano (halo de inibição > 13mm) dos extratos aquosos e etanólicos de moringa frente a S. aureus, V. cholerae e E. coli isoladas de camarão cinza Litopenaeus vannmaei. A cepa de E. coli isolada do pescado Oreochromis niloticus apresentou sensibilidade frente ao extrato etanólico de moringa. Os extratos aquosos de graviola apresentaram efeito bactericida frente a S. aureus e V. cholerae, entretanto, os extratos etanólicos dessa planta não mostraram atividade antibacteriana.
