Influence of some weak acids, weak bases and salts against some pathogenic microorganisms

الملخص EN

This study was designed to investigate of antibacterial activity of many chemical compounds includes : 4 % imidazole, 2 % imidazole, 1 % imidazole , 2.5 % sodium citrate, 5 % sodium citrate, 5 % sodium acetate, 2.5 % acetic acid, 5 % acetic acid, 5 % citric acid, 5 % magnesium chloride (MgCl2.6H2O2), 5 % magnesium sulphate (MgSo4), 5 % sodium carbonate (Na2Co3), 5 % potassium dichromate (K2Cr2O7), 5 % potassium permanganate (KMnO4) and 5 % sodium hydrogen carbonate (NaHCO3 ) have been carried out against (Escherichia coli, Pseudomonas aeruginosa, Klebsiella oxytoca, Proteus mirablis and Serratia liquefaciens ) that diagnosed by API 20 E technique and Staphylococcus aureus , Pathogenic fungal strains (Aspergillus niger, A.

flavus, A.

fumagatus, Fusarium sp.

and Candida albicans ).

The results showed 4 % imidazole, 2 % imidazole, 1 % imidazole, sodium acetate, 2.5 % acetic acid, 5 % acetic acid, 5 % citric acid, 5 % Na2CO3, K2Cr2O7 have different antibacterial activity according to types of bacteria, whereas 4 % imidazole, 2 % imidazole , 2.5 % acetic acid, 5 % acetic acid and 5 % Na2Co3 only have antifungal activity, and showed compounds : 4 % imidazole & K2Cr2O7 have antimicrobial activity more than standard positive control antibiotic.
