| Abstract: | Five species of Cypraea (Cypraea errones, C. arabica, C. onyx, C. tigris and C. vitellus) were assayed for their antibacterial and antifungal activity against 15 bacterial pathogens and 3 fungal pathogens. Antibacterial and antifungal activities were exhibited only by C. errones extracts. An ascidian, Didemnum psammathodes, the principal diet of C. errones was also assayed for antimicrobial activity to evaluate whether the activity exhibited by C. errones was derived from its diet. The ascidian extract exhibited broad-spectrum antibacterial activity. Chromatographic fractionation of the extracts of C. errones and Didemnum psammathodes confirmed that the activity exhibited by C. errones was not diet derived. |
