Several bacterial species associated with tonsillitis were isolated from the samarra general hospital, including Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. The extract of alcohol and water tea was used to observe its eff ect in inhibiting the growth of bacteria with the addition of 3 concentrations of NaCl (5, 7.5, 10 g/L ) to the medium used (Muller hinton agar, Nutrient agar), the results showed that the eff ect of S. aureus on the alcohol and water extracts and all the concentrations used in addition to the use of the muller hinton agar and the use of nutrient agar the result showed that the bacteria were aff ected by alcohol extract and all the concentrations used however when adding the water extract the eff ect of bacteria was observed when adding the third concentration of NaCl , The eff ect of E. coli was observed by alcoholic and water extract of tea with the addition of the third concentration of NaCl using the muller hinton agar and the use of the nutrient agar the growth of E. coli was observed by alcoholic extract only and by the addition of the third concentration of NaCl, The eff ect of the bacteria was observed with alcohol extract only for the tea and all the concentrations using the muller hinton agar and using the nutrient agar the eff ect of bacterial growth was observed by the extract when adding the third concentration of NaCl to the medium, we conclude are diff erences in the eff ect of extract on isolated bacterial species |
