A fatal case of Nocardia otitidiscaviarum pulmonary infection and brain abscess: taxonomic characterization by molecular techniques.

We report on a rare case of pulmonary Nocardiosis and brain abscess caused by Nocardia otitidiscaviarum in an elderly woman with chronic obstructive pulmonary disease. Taxonomic identification involved phenotypic testing, restriction fragment length polymorphism (RFLP), and complete 16S rRNA gene sequencing.
