Melioidotic pericardial effusion.

Aim is to present a rare case of purulent pericardial effusion caused by Burkholderia pseudomallei. Pericardial sample was inoculated into Bactec Peds Plus/F broth of the Bactec automated system. After the system flagged positive, the broth was subjected to Gram stain, biochemical tests and drug susceptibility. The organism was identified as Burkholderia pseudomallei. Tuberculosis (TB) is the most common cause of pericarditis in countries where it remains a major public health problem, but in the western coastal districts of India, clinicians and microbiologists alike must be aware of Burkholderia pseudomallei a rare cause of pericarditis that can be misdiagnosed as TB pericarditis.
