EXTRACTION AND CHARACTERIZATION OF TEICHOIC ACID FROM STAPHYLOCOCCUS AUREUS

Abstract

Teichoic acid has been considered as surface reactive antigen (immunogens, biological response modifiers), as well as membrane components which mediate the attachment of Staphylococcus aureus to host cell tissues . The teichoic acid was extracted and purified in this study from an isolate of Staphylococcus aureus and the chemical analysis of teichoic acid showed that it was rich in carbohydrates (55 %) with small amounts of proteins (17.5 %)
