Antibacterial Activity of Vanillic Acid against Staphylococcus aureus, Salmonella typhi, and Proteus mirabilis

Aim. This study investigated the efficacy of vanillic acid against selected pathogenic bacteria obtained from clinical samples. Method. The antibacterial collected samples was studied using a broth macrodilution method. minimum inhibitory concentration determined by treating each isolate with increasing amounts ranging 150 to 2000 µg/ml. Results. lowest concentrations found were 600 µg/ml for Staphylococcus aureus, Proteus mirabilis, and Salmonella Typhi, time-kill susceptibility test also demonstrated significant reduction in viable cells bacterial isolates this study. findings confirmed antimicrobial effect on growth its activity Typhi. Conclusion. Vanillic may provide solution alternate therapeutic choices diseases caused
