Disseminated nocardiosis caused by Nocardia elegans: a case report and review of the literature
- 86 Downloads
Disseminated nocardiosis is a rare disease mostly occurring in immunocompromised patients.
We report a case of disseminated nocardiosis in a diabetic patient with both pulmonary and cutaneous involvement. Nocardia elegans was isolated and identified using the 16s ribosomal RNA gene sequence data.
Clinical improvement was observed within 3 months after initiation of antimicrobial treatment with oral doxycycline, trimethoprim-sulfamethoxazole and intravenous penicillin, but the patient died 5 months later after arbitrary discontinuation of the treatment.
This is the first case report of disseminated nocardiosis caused by Nocardia elegans in China.
