Brown seaweed is one of the algal species that has been used as food, a source of nutritional supplements, and formulated for therapeutic and cosmetic purposes. This study evaluated the antioxidant and antistaphylococcal activities of topical fucoidan gel (TFG) from the Sargassum oligocystum. A completely randomized design was used, and the experimental protocol includes extraction, lyophilization, and characterization, quality testing, and biological assay. Physicochemical tests suggested that the lyophilized fucoidan is comparable with the properties of pharmaceutical-grade fucoidan. FTIR ch

Aliarcobacter butzleri is a Gram-negative bacterium associated with infections of the gastrointestinal tract and widely distributed in various environments. For successful infection, A. butzleri should be able to tolerate various stresses during gastrointestinal passage, such as bile. Bile represents an antimicrobial host barrier that acts against external noxious agents and consists of a variety of bile salts. The intestinal bile salts act as detergents involved in the antimicrobial host defense; although, on the bacterial side, they could also serve as a signal to activate virulence mechanis
