Evaluation the Antibacterial Activity of some Macro Algae Isolated from Baghdad-Iraq

Abstract Because of their aggressiveness and capacity to build biofilms, multidrug-resistant bacteria like Staphylococcus aureus present a global threat and cause chronic illnesses. This study focused on two different areas: first, it looked at the antibiotic resistance profiles and biofilm activity of bacteria isolates taken from wounds and newborns. Secondly, it investigated the possibility of using algal extracts as strong agents that combat bacteria and biofilm formation. Two algal extracts, Spirogyra and Oedogonium (Chlorophyta) methanol extract were examined separately for their antibacterial and antibiofilm properties. The antibacterial and antibiofilm qualities of the algal extract were assessed. Algal extracts may be useful as antibacterial and antibiofilm agents to treat illnesses that are resistant to drugs, according to this study. It is necessary to conduct further research in clinical applications.
