what is mupirocin ointment used for bacterial skin infections. It is effective against a variety of bacteria, including Staphylococcus aureus and Streptococcus pyogenes, commonly found in skin infections like impetigo, folliculitis, and minor wounds. Mupirocin works by inhibiting bacterial protein synthesis, thus preventing the growth and spread of bacteria on the skin. It is typically applied directly to the affected area of the skin, usually two to three times a day, as directed by a healthcare professional. It's important to complete the full course of treatment even if symptoms improve to ensure the infection is fully eradicated.
