Fatal community-acquired Bacillus cereus pneumonia in an immunocompetent adult man: a case report.

ABSTRACT:

Background

Bacillus cereus is a gram-positive rod bacterium that is responsible for food poisoning. It is naturally widely distributed, and thus often contaminates cultures. Although it is rarely considered responsible, it can cause serious infections under certain conditions. However, lethal infections, especially in immunocompetent patients, are rare.
