Localized nocardiosis due to Nocardia caviae in a baboon (Papio cynocephalus).

Nocardia caviae was identified as the causative agent of draining, multinodular swelling of the hand of a 16-yr-old female baboon (Papio cynocephalus). The baboon's general physical condition was poor and menstrual cycles had ceased. The baboon improved after systemic and topical antibiotic therapy, but the lesion recurred after antibiotic treatment was discontinued. Since excision of the mass, the baboon's physical condition has improved to the extent that regular menstrual cycles have resumed and she has been returned to the assigned investigative program. Radiographs of the lungs, hand, and arm failed to disclose evidence of dissemination of the infection.
