Successful surgical management of a pyothorax in a Guinea baboon (Papio papio).

A 16-year-old male Guinea baboon (Papio papio) was evaluated for weakness and focal wet fur of 1-week duration. A pyothorax caused by Streptococcus anginosus was diagnosed. A surgical approach was chosen, combined with a systemic antibiotic therapy. Medical imaging and C-reactive protein follow-up revealed the resolution of the pyothorax.
