Ninety eight urine specimens were collected from patients suffering from
urinary tract infection in the Educational Hospital for Al–Diwaniya city/Iraq .
Results showed that 79 specimen reveal significant bacterial growth, while 19
specimen have no bacterial growth. Results of bacterial isolation and
identification of the bacteria were as follows :
Escherichia coli 43.03 % , Proteus mirabilis 20.25% , Klebsiella Pneumoniae
17.72 % , Pseudomonas aeruginosa 11.39 % Staphylococcus aureus 7.59 % .
Antibacterial effects of ethanolic and aqueous extracts of some medicinal
plants included: Allium sativum , Mentha longifolia , Nigella sativa L . and
Myrtus communis were measured by disc diffusion method. The results showed
variable inhibitory actions depending on the type of solvent, the concentration ,
the plant species and the bacterial species .
Depending on the type of solvent, ethanolic extract has the highest inhibitory
effect(largest inhibition zones) compared with Aqueous extract.
Depending on the concentration of extract, the antibacterial effectiveness of all
extracts increases with the increasing in it' s concentration.
On one hand, different plants have different antibacterial effect, Allium sativum
has the highest antibacterial activity more than the other studied plants.
On the other hand, the sensitivity of studied bacteria was variable,
Staphylococcus aureus has the highest sensitivity, following by Proteus
mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae. While Escherichia
coli has the lowest sensitivity
