Disseminated nocardiosis caused by Nocardia otitidiscaviarum-A case report.

In this article we report a case of disseminated nocardiosis caused by Nocardia otitidiscaviarum in an immunocompetent patient with chronic obstructive pulmonary disease (COPD) who complained of a cough, followed by skin and intracranial lesions. On metagenomic next-generation sequencing (mNGS) technology of respiratory samples (bronchoalveolar lavage fluid, BALF) Nocardia otitidiscaviarum was identified. The patient was treated with therapy combined with a low dose of TMP-SMX and imipenem cilastatin sodium and had a favorable outcome. The timely diagnosis of Nocardia with the help of mNGS technology and early rational treatment of TMP-SMX can help improve the prognosis.
