Acacia Confusa as an Alternative Antibacterial Agent Against Staphylococcus Species Using in Vitro Method.

CHAPTER 1 INTRODUCTION One of the most common infections that we can easily get was skin infections caused by bacteria, specifically Staphylococcus aureus and Staphylococcus epidermidis. These two Staphylococcus species can found worldwide, they are a small component of soil microbial flora. We have different treatments for skin infections, but in those treatments only few people can afford it. Because most of them are expensive for ordinary people who are usually experiencing skin infections because of their work, the farmers who are exposed on fields without wearing a proper gear for them to be protected from wounds. We are lucky because our country was rich with different trees, which are not just giving us oxygen, shade, and woods for our furniture. Trees can give us also their medicinal property to help us. One of the examples is Acacia confusa, the most common specie of acacia tree here in the Philippines. Acacia is a genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae. Acacia have possible uses in folk medicine and pharmaceuticals. On this study we use the bark of the acacia tree as the raw material to produce an alternative antibacterial agent against Staphylococcus species such as Staphylococcus aureus and Staphylococcus epidermidis using in vitro method.
