Antimicrobial activity of some crude marine Mollusca extracts against some human pathogenic bacteria

الملخص EN

The antimicrobial activity of three species of marine Mollusca extracts, Sepia sp., Loligo sp.

and marine snail Tibia insulaechorab-curta marked as S, L and T respectively were studied against five bacterial species of family Enterobacteriaceae (Escherichia coli, Pseudomonas aeruginosa, Klebsiella oxytoca, Proteus mirablis and Serratia liquefaciens ) that diagnosed by API 20 E technique.

S & T extracts exhibited significant differences to good antimicrobial activity more than L extract.

All bacteria were tested have shown susceptible to S and T extracts, Antibacterial sensitivity test of 6 antibacterial antibiotic showed the crude extracts clear effect more than the antibacterial antibiotic.

The minimal inhibitory concentration of all extracts were detection.
