What are the treatments for Micrococcus luteus infection?

Micrococcus luteus infections are typically treated with antibiotics that target gram-positive bacteria. The first-line treatment usually involves penicillin-based antibiotics such as amoxicillin (500 mg three times daily for 7-10 days) or ampicillin (500 mg four times daily for 7-10 days). For patients with penicillin allergies, alternative options include erythromycin (500 mg four times daily for 7-10 days) or clindamycin (300-450 mg four times daily for 7-10 days). In more severe cases or for immunocompromised patients, vancomycin (15-20 mg/kg IV every 8-12 hours) may be necessary. Antibiotic susceptibility testing is recommended to ensure effective treatment, as some strains have developed resistance. Complete the full course of antibiotics even if symptoms improve to prevent recurrence. Micrococcus luteus is generally susceptible to these antibiotics because it has a relatively simple cell wall structure compared to gram-negative bacteria, allowing antibiotics to penetrate more easily and disrupt cell wall synthesis or protein production. Most infections are mild and respond well to treatment, though immunocompromised patients may require more aggressive therapy and monitoring.
