A 3-year-old neutered female poodle was brought to the vet because she was very tired, not eating, and losing weight. Tests showed that she had swollen lymph nodes in her abdomen and signs of a serious infection caused by a type of bacteria and fungus. The vet tried treating her with antibiotics, but unfortunately, her health continued to decline, and she passed away about three weeks after her first visit.

Abstract

A 3-year-old neutered female poodle with a long history of dermatophytic skin disease was presented with lethargy, anorexia and progressive weight loss. Abdominal ultrasonography revealed markedly enlarged mesenteric lymph nodes and multiple hypoechoic foci in the spleen. Cytology of the mesenteric lymph nodes and spleen showed granulomatous inflammation with fungal organisms and negatively stained intracytoplasmic bacterial rods consistent with Mycobacteria spp. Based on culture, multiplex polymerase chain reaction and sequence analysis, the bacterium was identified as Mycobacterium avium subspecies hominissuis. Despite treatment with antibiotics, the dog's condition deteriorated, and it died approximately 3 weeks after first presentation.
