Antimicrobial effect of protein(s) isolated from a marine mollusc Telescopium telescopium.

ABSTRACT

Ammonium sulfate precipitated protein (SF-50) isolated from the spermatheca gland of Telescopium telescopium, an invertebrate marine snail, showed antimicrobial effect on Escherichia coli. The antimicrobial effect varied with the concentration of "SF-50" used and the effect was found to be comparable to antibiotics like amikacin, contrimoxazole and gentamycin in disc diffusion test. The "SF-50" was devoid of erythrocyte haemolysis property.
