The main focus of this study was to determine the antibacterial effect of Neem tree (Azadirachta indica) leaf extract on Staphylococcus aureus. The Neem tree leaf extract was tested in terms of the different levels of concentration with (a) 25% concentration, (b) 50% concentration, (c) 75% concentration, (d) 100% concentration on Staphylococcus aureus. It specifically compared the significant differences of the different levels of concentration of Neem tree leaf extract, and also compared to the positive control. The plant materials were collected and brought to the West Visayas State University Biological Science Laboratory where the experimentation was conducted.
Completely Randomized Design (CRD) was the research design used in the study. The interpretation of the results was based on the Claustro et.al zone of inhibition scale. The statistical analysis (One- way ANOVA) was not employed due to the reason that the zone of inhibition is zero.
Results of the study revealed that there was no significant differences on the effect of the different levels of Neem tree (Azadirachta indica) leaf extract on Staphylococcus aureus.
