Effect of aqueous extracts of plants in a group of bacteria that cause diarrhea

Abstract

Sensitivity of the bacteria have been studied fo extract boiled and cooled water for five types of plants, plant extracts tea (TheaSinensis) and The baker (Malvapazvifloza) and the plant extract is amixture of the last three plants are (Nigella staiva) , (Allium staivum) and (citrus aurantifolia) . Extracts used boiled and cooled water to plants when you concentration (250 , 500 , 1000 ) mg / ml . The disk diffusion method used saturated with plant extracts according to the method to test the sensitivity of bacteria (E.coli , salmonella , shigella) . that cause diarrhea for different age groups has been observed that the aqueous extract of mixture(citrus aurantifolia ,Allium staivum , Nigella staiva ) . Has a clear inhibitory effect through inhibition zone diameter in the growth of bacteria studied .
