title: [Four cases of respiratory tract infections caused by Corynebacterium pseudodiphtheriticum].
abstract: Four cases of respiratory tract infections caused by Corynebacterium pseudodiphtheriticum were reported. The first two patients developed pneumonia with Corynebacterium pseudodiphtheriticum during steroid therapy used against their underlying diseases. The other two patients had acute exacerbation of chronic pulmonary diseases caused by C. pseudodiphtheriticum. These four patients improved by antibiotic therapy. Though nondiphtheria corynebacteria are regarded as "normal flora" when they are isolated from sputum, they should be recognized as potential pathogens.
