Molecular identification of a Nocardiopsis dassonvillei blood isolate

Nocardiopsis dassonvillei is an environmental aerobic actinomycete seldom i solated in cutaneous and pulmonary infections. We herein report the first N . dassonvillei blood isolate in a patient hospitalized for cholangitis. Alt hough morphological characteristics and biochemical tests allowed a presump tive identification of this isolate, cell wall fatty acid chromatographic a nalysis confirmed identification at the genus level, and 16S rRNA gene sequ encing achieved definite identification. This study illustrates the usefuln ess of 16S rRNA gene sequencing as a routine method for the identification of actinomycetes.
