Abstract

Crude extracts of marine Mollusca Sepia sp. ,Tibia insulaechorab-curta and Thais sp.
marked as A, B and C respectively, using 50 % acetic acid were studied for their antifungal
activity using agar well diffusion technique against seven fungi (Aspergillus niger, A. flavus,
Candida albicans , C. krusei, C. tropicalis , C. famata & C. guilliermondii ). No antifungal
activity was recorded against A. niger &A. flavus in all concentrations of Thais sp. extract.
Sepia sp. & Tibia insulaechorab-curta extracts exhibited significant differences (P≥0.05) to
good antifungal activity more than Thais sp. extract. An extract has been showed high activity
against C. albicans (inhibition zone=27.6 mm) diameter, and minimum zone of inhibition
(16mm) was recorded against growth A. niger of same extract. In B extract, maximum
inhibition zone (26.6mm ) in growth A. flavus & C. albicans and minimum inhibition zone
diameter (15mm) in growth A. niger .Also the minimal inhibitory concentration of all extracts
were detected .The results showed the inhibition zones diameter of Fluconazole as positive
control approximately with the inhibition zones of crude extracts .
