Abstract
Propolis extracts have biological importance which can be utilized to overcome the dropped efficiency of some medicines such as antibiotics. This study included the biological activity of different concentrations of ethanol extract of Iraqi propolis against three species of bacteria, which have been isolated and identified from cows infected with mastitis and pneumonia in the Department of Veterinary Internal and Preventive Medicine, College of Veterinary Medicine, University of Baghdad. The identified bacteria included Staphylococcus aureues, Escherichia coli and Klebsiella pneumonia. Results showed that ethanol extract of Iraqi propolis at concentration of 5 mg/ ml was more active to inhibit the growth of Staph. aureus , E. coli and K. pneumonia by agar diffusion technique. Wherein, inhibition zone diameters attained 22.30, 20.0 and 19.30 mm respectively. The inhibition caused by the concentration of 5 mg/ml of propolis against E. coli and K. pneumoniae was significantly equal with the 0.1 mg of gentamycin. While the growth of Staph. Aureus have been inhibited by the eraqi propolis conce tration of 5 mg/ ml and was statistically surpassed the 0.1 mg gentamycin, inhibition. Statistically the concentrations of 2-5 mg/ml of propolis were superior to inhibit the growth of all studied bacteria by agar diffusion technique in comparing with control treatment
