In this episode Dr. G explores fusidic acid — an antibiotic isolated from the Fusidium fungus — its unique mechanism blocking elongation factor G, and why it became a powerful tool against Staphylococcus aureus in skin and wound infections.

Dr. G covers clinical uses (topical creams, oral and IV when combined with rifampicin ), availability issues in the U.S., and why stewardship matters: short-term topical use only, culture-guided therapy, and avoidance of prolonged monotherapy to prevent rapid resistance.
