Marine sponge secondary metabolites paid more importance because of their unusual bioactive chemical compounds. In the present study aims to determine the antimicrobial potential of three marine sponges such as Clathria (Clathria) gorgonoids, Callyspongia sp., Sigmadocia carnosa collected from south peninsular coast of India. The antimicrobial effects of these sponge extracts were assayed against a test panel of pathogenic bacteria. The test panel consisted of 10 strains including Bacillus subtilis, Eschirichia coli, Staphylococcus mutants, Streptococcus aureus, Proteus vulgaris, Shigella sp, Salmonella typhi, Mycobacterium sp, Klebsiella pneumonia and Enterobacterium sp. Bioassay results revealed that Sigmadocia carnosa species (90%) exhibited antibiotic activity against most of the bacterial isolate followed by Clathria (Clathria) gorgonoids.
