Main Article Content
Abstract
Forty Pseudomonas aeroginosa isolates isolated from Baghdad hospitals from different clinical specimens identified by morphology and biochemical tests then confirmed by vitek system . Different antibiotics used against isolates like ampicillin ,levofloxacin ,gentamycin , meropenem and ceftazidim ,the results showed that there were 100% of bacterial resistance to ampicillin, and gentamycin while 50% of resistance to ceftazidim , 10% of isolates had resistance to levofloxacin and meropenem. Minimal inhibitory concentration for alcoholic extract of Syzygium aromaticum was prepared and used against bacterial isolates, it had inhibition effect on bacteria in 200 mg/ml , and 100 mg/ml gave diameter of inhibition zone rang 12-18mm and 4-6mm respectively. Minimum inhibitory concentrations of plant extract were 200-100 mg/ml . Syzygium aromaticum extract had agood antibacterial activity on P. aeruginosa
