A COMPARATIVE STUDY OF THE IN VITRO ANTIBACTERIAL ACTIVITY OF ENDOCARP, DATE PALM TISSUE AND DATE PALM TISSUE WITH ENDOCARP TOGETHER AGAINST SOME GRAM NEGATIVE AND GRAM POSITIVE PATHOGENIC BACTERIAAbstract
The antibacterial activities of water extracts of the three major parts of the date palm fruit were compared against Eschereshia coli; Klebsiella pneumonia; Salmonella enteritidis; Pseudomonas aeruginosa; Staphylococcus aureus using the agar well diffusion method. Endocarp extract showed a wide range of activity against all Gram negative bacteria while it exhibited a low activity against Gram positive bacteria.The date tissue and endocarp didn’t show any activity against Klebsiella pneumoniae with a low or no activity against Pseudomonas aeruguinosa. Date tissue extract alone didn’t exhibit any activity against Klebsiella pneumoniae and Pseudomonas aeruguinosa. All types of extract were active against Escherichia coli. A consistently lower susceptibility of Klebsiella pneumonia and P. aeruginosa indicated its capability for developing resistance against various antibacterial substances. Antibacterial activities displayed by all extracts especially the endocarp also signified their remarkable potential for exploration of effective natural antibacterial agents against common pathogenic bacteria.
