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

Gauging the laboratory responses to coronavirus disease (Covid-19) in Africa

The rampaging effect of coronavirus disease (COVID-19) in Africa is huge and have impacted almost every area of life. Across African states, there exist variations in the laboratory measures adopted, and these heterogeneous approaches, in turn, determines the successes or otherwise recorded. In this study, we assessed the various forms of laboratory responses to the containment, risk analyses, structures and features of COVID-19 in high incidence African countries (Nigeria, South Africa, Egypt, Ghana, Algeria, Morocco, etc.) to aid better and efficient laboratory responses to the highly infectious diseases
