Abstract

Rhodococcus equi-associated necrotizing lymphadenitis in a llama.

Abstract

Rhodococcusequi-associated caseous necrosis, resembling macroscopically that seen in ovine caseous lymphadenitis, was observed diffusely in the tracheobronchial and mediastinal lymph nodes, and in an extensive lesion in the lungs of a 2-year-old male llama. Necrosis was present to a lesser extent in the spleen and hepatic and gastric lymph nodes. Numerous bacteria-laden macrophages were present around the necrotic areas.
