Abstract

Abstract

The aim of this study was to know the effect of water and alcohol extracts of two medicinal plants, Myrtle and Green Tea, in inhibiting the growth of two types of bacteria: Pseudomonas aeruginosa and Escherichia coli.  The study also tested the resistance of bacterial isolates to Tetracyclin antibiotic. The pH of leaves of alias and green tea was measured.

Gradient concentrations of each plant extract were used to determine the concentrations in which the bacteria showed their growth, which gave a vitality almost equal to the control group.  The study concluded that:

The water extract of Myrtle leaf and green tea was found to be effective in reducing the growth of bacteria at concentrations (10, 20, 30) and (10, 15, 20%) compared with the alcoholic extract of both plants which was less effective.

The antibiotic showed a clear inhibitory effect on E.coli at concentration (0.1) ml while P. aeruginosa showed clear antibody resistance.
