Clinical manifestations range from localized skin abscess to severe pneumonia and sepsis. While considered rare, the bacterium can remain latent for decades, making melioidosis a critical differential diagnosis for those with exposure risk, both recent and remote. Laboratory identification requires culture under BSL-3 precautions, and treatment mandates a prolonged, biphasic approach to prevent relapse.MedicineArticleSCOPUS10.1016/j.clinmicnews.2026.05.0022-s2.0-10503916648018734391
