Invasive infection due to Moraxella lacunata, an unusual pathogen.

Moraxella lacunata, a commensal bacterium, is associated with serious invasive disease. We describe a patient with diabetic nephropathy who developed septicemia with metastatic abscesses in the liver and spleen due to Moraxella lacunata. The patient also had multiple ring enhancing lesions in both the cerebral hemispheres, possibly due to the same organism.
