In most underdeveloped nations, traditional medicine, including herbal treatment, is still widely used. Due to the growth of antibiotic resistance, this study aims to use pepper as an anti-bacterial as alternative to antibiotics. Pepper is one of the most important plants used as a medicine for a long time in various countries and civilizations. This study aims to use pepper as an anti-bacterial in alternative to antibiotics.
The current study included the inhibitory efficacy of aqueous and alcoholic red pepper extract on seven bacterial isolates: -Staphylococcus aureus, Streptococcus spp, Escherichia coli, Klebseilla spp, Salmonella spp, Pseudomonas aeruginosa, Proteus spp. These isolates were isolated from different pathologies and regions, and they were diagnosed according to the site of infection. Several antibiotics were also used as a standard control sample for germs.
This study shows that the highest inhibitory Effect against E. coli bacterium, as the average inhibition diameter was about 16.5 mm, and it is an excellent inhibitory when compared to the antagonist's gentamicin and nitrofurantoin as it showed good inhibitory efficacy against the bacteria such as S. aureus P. aeruginosa, and Salmonella spp. While the effect on Klebsiella was equal, on the other hand, the aqueous extract did not show any efficacy against Proteus spp, as was shown in the results. The results also showed that Staph. Aureus bacteria were the most affected by the alcohol extract of the red pepper as it showed a high inhibition zone compared with the control sample tetracycline and nitrofurantoin. The plant's aqueous and alcoholic red pepper extracts were effective against the tested bacterial isolates. The plant's aqueous and alcoholic red pepper extract has good inhibitory efficacy against the studied bacterial isolates.
