Abstract EN

Bacteria are microorganisms found in the environment surrounding us, and they play an important role in many vital processes.

However, some bacteria may be pathogenic and pose a threat to public health.

This calls for the need to search for effective natural means to combat these pathogenic bacteria.

One of these potential methods is the use of Ziziphus plant extracts.

The study aimed to evaluate the effectiveness of the alcoholic extract of the plant and the success of the identification of the cercariae on a variety of laboratory species, as well as to test the antagonistic effectiveness of the extract on homogeneous bacteria in the medium using the method of spreading on discs.

To achieve the objectives of the study, experimental and analytical models were used to contribute the results to the production of Ziziphus on some types of bacteria.

The study concluded that there was antibacterial activity against the tested bacteria and that it was very effective in reducing their growth and reproduction on agricultural dishes, with the exception of the aqueous extract, which did not show any significant effect.

There is a variation between the extracts and concentrations depending on the duration of incubation, and increasing the concentration has the effect of increasing the inhibitory effect.

The results showed the effectiveness of the alcoholic extract of the Ziziphus plant (leaf) as an antibacterial agent on bacteria, and the presence of good inhibitory activity of the alcoholic extract for all types of bacteria at a concentration of 50%.

The diameters of the inhibition zone for Bacillus bacteria at all concentrations used ranged from 15 mm to 27 mm.

The study indicated that the inhibitory ability of the alcoholic extract of the Ziziphus plant (date + kernel) on the tested bacteria at various concentrations was more inhibitory on Staphylococcus and Pseudomonas bacteria.

The diameters of inhibition were 24.5 mm and 21.5 mm, respectively, for the alcoholic extract.

While the extract did not show any significant effect on coliform bacteria at various concentrations, most of the tested bacteria were resistant to antibiotics, with the exception of the antibiotic Imipenem, which showed great effectiveness on all isolates, followed by Chloramphenicol and Amoxicillin.

As for the bacteria, the most sensitive was Bacillus bacteria, followed by Shigella and Staphylococcus, while Staphylococcus Bacillus bacteria were resistant to the antibiotics Cefadroxil and Imipenem, respectively.

This resistance may be due to the indiscriminate and irregular use of antibiotics.
