Antibacterial activity of an aqueous extract of Petroselinum crispum leaves against pathogenic bacteria isolated from patients with burns infections in Al-najaf Governorate, Iraq

The purpose of this study was to investigate, by use of the agar well diffusion method, the ability of cold-water and hot-water extracts of Petroselinum crispum leaves to inhibit bacteria isolated from patients with burns infections. The results revealed that 250 mg/ml of the hot-water extract was the more effective inhibitor of the growth of P. aeruginosa. The inhibition zone diameter of 29.667 mm was significantly different (P < 0.05) from that for nitrofurantoin, chosen as positive control. From the overall results obtained it is evident that the plant screened has anti-bacterial activity against some bacteria associated with burns infections.
