| ABSTRACT Two species of sponge i.e., Xenia macrspiculata and Clathria arbuscula, as well as one species of coral, i.e., Crella (Grayella) cyathophora representing marine invertebrates were collected from the Red Sea, Hurghada, Egypt. The antibacterial activities of their crude extracts was investigated against, Against G+ve bacteria namely, Staphylococcus aureus (NIOF-B16), enterococcus faecalis(NIOF-B21) and Bacillus cereus (NIOFB33) as well as G-ve ones namely, E. coli(NIOF-B17), Vibrio fluvial(NIOFB24), Pseudomonas aeroginosa(NIOF-B23), and Salmonella ttyphimurium (NIOF-B35).The extracts were screened for the presence of compounds such as terpenoids, tannins, anthocyanins, glycosides, phenols, flavonoids and alkaloids that could be responsible for bioactivity. The extracts exhibited an antibacterial effect against the all of the examined strains, resulting in average inhibition zones ranging between 8.0 ± 0.1 and 20.0 ± 0.3 mm. The presence of steroids, terpenes, phenols, alkaloids, and tannins found in the extract fractions seemed to be the cause of the wide spectrum antibacterial activity of these sponges Most likely, this is the first report on Xenia macrspiculata, Clathria arbuscula, and Crella (Grayella) cyathophora's antibacterial activity. | ||||
