INHIBITORY POWER TEST OF MEDICINAL PLANTS EXTRACT AGAINST BACTERIAL GROWTH METHICILLIN RESISTANT STRAINS OF Staphylococcus aureus (MRSA)

摘要

Staphylococcus aureus is a normal flora in the human body, but if the bacteria is not in its proper place, it will lead to infection. S. aureus infections are treated with antibioticsβ-lactam class, has a drug target in the cell wall. Bacteria strains of S. aureus are already resistant to Methicillin Resistant called Staphylococcus aureus (MRSA). One of the alternative that can be used is by using medicinal plants. It is necessary to see the ability of bacterial strains of MRSA. This study aims to determine the good inhibitory effects of plant extracts drug against MRSA strains of bacteria growth. This study is an experimental study with 9 treatments and 3 replications of medicinal plants, which performed at the Laboratory of Microbiology, Faculty of Mathematics Natural Sciences, Padang State University from April to May 2009. To determine the inhibition of medicinal plantsextracts,was done by observing diffusionmethod of inhibition zone of each medicinal planta. By calculating the average diameter of the inhibition zone formed and conducted analysis ANOVA test. The results showed that all the medicinal plants can inhibit the growth of MRSA strains of bacteria with inhibition zones formed on each treatments. Allium sativum extract capabilities (garlic) and Curcuma domestica (turmeric) is better than Amphicillin, whereas other medicinal plants have the same ability to Amphicillin.
