Melioidosis: (Psuedomonas pseudomallei)

Clinical:

Melioidosis is a tropic disease that prevails in parts of Southeast Asia. There are four forms of infection- acute fulminant septicemia, subacute illness, chronic infection, and subclinical disease. Acute melioidosis is often a fulminant infection with sepsis and hematogenous dissemination. Mortality is high. Subacute infection usually presents as an indolent upper lobe pneumonia which sometimes cavitates. This is the most common form of infection. Chronic disease can produce abscesses in multiple organs and pulmonary involvement is characterized by apical cavitary disease. Depending on the form of infection, radiographic findings include airspace consolidation, lung abscess, nodular densities which sometimes cavitate, and less commonly pleural effusions.
