Biological Application of New Organic Derivatives on Bacterial Growth

The growth of strains of deferent types of pathogenic bacteria isolated from different sites of infection , Escherichia coli ,klebisiella pneumonia ,staphylococcus aurous ,staphylococcus epidermis , streptococcus pneumonia, streptococcus agalactiae , streptococcus mutans , has been investigated about inhibitory effect of new synthesized complex organic compound consisting of ( Ni +2 or Co +2 ) . The results reveled that cobalt (II) complex which contain chelating dicarboxylate ligands has action inhibitory effect on such pathogenic bacteria while Ni ( II) Shows no effect even in highly concentration but only on the streptococcus agalactiae . Key word : Pathogenic bacteria , Diacetic acid derivative , antibacterial activity .
