| Abstract: | A 3-year-old neutered female poodle with a long history of dermatophytic skin disease waspresented with lethargy, anorexia and progressive weight loss. Abdominal ultrasonographyrevealed markedly enlarged mesenteric lymph nodes and multiple hypoechoic foci in thespleen. Cytology of the mesenteric lymph nodes and spleen showed granulomatousinflammation with fungal organisms and negatively stained intracytoplasmic bacterial rodsconsistent with Mycobacteria spp. Based on culture, multiplex polymerasechain reaction and sequence analysis, the bacterium was identified asMycobacterium avium subspecies hominissuis. Despite treatment withantibiotics, the dog’s condition deteriorated, and it died approximately 3 weeks afterfirst presentation. |
