First successful treatment of Nocardia farcinica brain abscess with moxifloxacin.

Nocardia farcinica is an emerging pathogen in immunosuppressed patients causing both localized and disseminated infections. Many strains of this species are multidrug-resistant and require long-term antibiotic therapy, and consequently the choice of an oral treatment can be problematic. We report here the first case of successful treatment of N. farcinica brain abscess in a renal transplant recipient with an extended-spectrum fluoroquinolone, moxifloxacin.
