A case of systemic melioidosis: unravelling the etiology of chronic unexplained fever with multiple presentations.

Abstract

Melioidosis, caused by the environmental saprophyte, Burkholderia pseudomallei, is an important public health problem in Southeast Asia and Northern Australia. It is being increasingly reported from other parts, including India, China, and North and South America expanding the endemic zone of the disease. We report a case of systemic melioidosis in a 58-year-old diabetic, occupationally-unexposed male patient, who presented with chronic fever, sepsis, pneumonia, pleural effusion and subcutaneous abscess, was undiagnosed for long, misidentified as Pseudomonas aeruginosa infection elsewhere, but was saved due to correct identification of the etiologic agent and timely institution of appropriate therapy at our institute. A strong clinical and microbiological suspicion for melioidosis should be considered in the differential diagnosis of acute pyrexia of unknown origin, acute respiratory distress syndrome and acute onset of sepsis, especially in the tropics.
