The mucin obtained from body surface mucus of African giant snail, Achatina fulica Bowdich 1822, was examined for its antibacterial activity. The water soluble fraction (WSF) and the mucin fraction (MF) of the mucus exhibited positive antibacterial activity for Staphylococcus aureus and Proteus vulgaris but negative antibacterial activity for Escherichai coli, Pseudomqnas aeruginosa, Bacillus subtilis, Krebsiella pneumoniae, Enterobacter aerogenase and Shigella boydii. The minimal inhibitory concentration (MIC) of MF for S.aureus and P.vulgaris are 16 and) 64 mcg/ml, respectively.
