Bacteremic pneumonia caused by Nocardia veterana in an HIV-infected patient.

Disseminated Nocardia veterana infection has rarely been reported. We describe the first reported case of N. veterana bacteremic pneumonia in an HIV-infected patient. The isolate was confirmed by 16S rRNA sequencing analysis. The patient initially responded well to trimethoprim-sulfamethoxazole treatment (minimum inhibitory concentration 0.25 μg/ml), but died of ventilator-associated pneumonia.
