Some 6f the marine organisms have been found to possess chemotherapeutic properties. The active ingredients can be used as antibacterial, antifungal: antitumor and antiviral agents. These compounds are sometimes difficult to be synthesized in laboratory. Since very little work has been done in the past on the organisms found in the Red Sea, therefore some sponges and gorgonians were collected from the sea near the coast of Jeddah. Our results indicated that Sh. body, E. coli, and S. aunts, exhibited susceptibility to some crude extracts of sponges and gorgonians. Ampicillin, Amoxicil1in and Cefuroxime were used as standard drugs. During the screening of antifungal activity. it was noted that Lizella ._p. all Axil1ellida sp. showed significant activity against C. II/null/, T. longijiw/s and M. call is. Myconazole, and Ketoconazole were used as standard drugs for comparison.
