Abstract

This research was conducted to study the antibacterial activity of some Palestinian plants against seven human pathogenic bacteria using the agar disk-diffusion method. Evaluation of the antibacterial activities of plant saps based on the width of the bacterial inhibition revealed that Eucalyptus camaldulensis (0.3 cm), Allium sativum (0.2 cm), Ceratonia siliqua (0.15 cm) and Amygdalus communis(0.15 cm) have the best antimicrobial activities against the bacterial mixture compared with the other fourteen tested plants. Furthermore, E. camaldulensis showed the strongest antimicrobial activity among the four plants. Also, A. sativum have the maximum anti-microbial action against all types of the tested bacteria. In addition, saps of E. camaldulensis and the mixture of E. camaldulensis and A. sativum have a strong ability to kill all types of the tested bacteria followed by the mixture of C. siliqua and A. sativum, the mixture of C. siliqua, A. sativum and E. camaldulensis and the mixture of A. communis, A. sativum and E. camaldulensis that have significant results as anti-microbial agents against most types of the tested bacteria. The results showed that A. sativum and the mixture of A. sativum and C. siliqua have the maximum antimicrobial affectivity against Staphylococcus aureus, whereas, Micrococcus luteus was strongly inhibited by E. camaldulensis, A. sativum, the mixture of E. camaldulensis and C. siliqua, the mixture of E. camaldulensis and A. sativum, and the mixture of E. camaldulensis, A. sativum and C. siliqua. Escherichi. coli was efficiently inhibited by A. communis, A. sativum, and E. camaldulensis and also by the mixture of A. sativum and E. camaldulensis. Pseudomonas aeruginosa was inhibited in a significant amount by E. camaldulensis and A. sativum, whereas, Proteus vulgaris was strongly inhibited by the A. sativum. Bacillus subtilis was strongly inhibited by A. sativum, while, for the Klebsiella pneumoniae, most saps revealed an intermediate inhibition except the A. communis, which showed the lowest inhibition value. Therefore, the current study elucidated that E. camaldulensis, A. sativum, C. siliqua and A. communis are the best tested Palestinian plants containing the antibacterial agents against the tested bacterial types.
