Study the effect aqueous and alcoholic extracts of green tea on some bacterial isolates from infections of urinary tracts

Abstract

    Collected 100 samples from patients infected with generation of urinary tract infection acute and chronic, isolated 85 bacterial isolates them, and diagnosed to the following types using biochemical tests and test the API, has been diagnosed by the E.coli (20%), K.pneumoniae (15%), and the genus Enterobacter cloacae (10%), and the bacteria Pseudomonas aeruginosa (5%), while the isolates were positive for the dye Cram One was Staphylococcus aureus (10%) and Staphylococcus epidermidis by (8%). Isolates tested for sensitivity (10) an antibiotic, bacterial isolates have shown a difference in the rates of resistance to these antibiotics.

    Bacterial isolates were selected on the basis of the most frequency in urinary tract infections and their resistance to the impact of antibiotics that are: (E. coli and K.pneumoniae Enterobacter cloacae and Ps.aeruginosa and, Staph.aureus, Staphylococcus epidermidis). The selection effect of water and alcoholic extracts of green tea leaves in the growth of the isolates at concentrations (25, 50, 75 and 100) mg / ml. The results showed that alcoholic extract of the plant cold green tea is more efficient than the other extracts influencing on the growth of pathogenic bacteria by used (The Agar – Well Diffusion Method).
