Information's on the potency of many medical plants against microorganisms are scanty, and in the current wave of antimicrobial resistance against chemotherapeutic drugs, there is a need to search for plants that could be resistance-free and affordable.
The objective of this study was to investigate the antibacterial effects of Parsley (Petroselinum crispum) against uro-pathogens and to compare with the effect of some drugs used for the treatment of urinary tract infection caused by different Gram positive and Gram negative bacteria.
MATERIALS & METHODS:
A total of thirty eight Gram positive and Gram negative bacteria(Escherichia coli ,Proteus sp.,Enterobacter spp.,Pseudomonas aeruginosa, Klebsiella sp. , Staphylococcus aureus) isolated from urine samples of different child patients between first of June 2011 to first of July 2011 admitted to Children Mel fare Teaching Hospital in Baghdad were tested against different dilutions of Parsley (100%,1:1,1:5,1:10:1:15,1:20) to examine the inhibitory activity in vitro ,in addition antibiotic susceptibility test was done.
All isolates showed sensitivity to concentrated parsley 100% concentration except Pseudomonas aeruginosa isolates, the highest effect observed on Proteus sp. and Staphylococcus aureus isolates, while inhibitory effect stopped after 1:1 dilution against all isolates, while in antibiotics therapy (29) isolates were resistant to Co-Trimoxazole and Cefotaxime and (30)isolates showed resistance to Tri-imetheprim+clavulanic acid.
It seems that Parsley has potent antibacterial activity against some uropathogens in vitro.
