Investigation antibacterial effect of euphorbia plant against different types of bacteria

In the present study, antibacterial activity assays were conducted using the extract of Euphorbia lucida Waldst. & Kit. against a range of bacterial strains. The efficacy of different dosage of the plant extract against different bacterial species was evaluated employing the disk diffusion method. The tested microorganisms included Klebsiella pneumoniae, Pseudomonas fluorescens, Salmonella kentucky, Listeria innocua, Serratia marcescens, Staphylococcus aureus, Bacillus subtilis, and Escherichia coli. The results demonstrated that Euphorbia lucida Waldst. & Kit extract exhibits notable antibacterial activity, with the most pronounced inhibitory effects observed against Bacillus subtilis (29.35 mm) and Klebsiella pneumoniae (24.95 mm). These findings suggest the potential utility of Euphorbia-derived compounds in both medical and environmental disinfection applications.
