Original publication title: First Description of Atypical Aspergillus floccosus as Cause of Canine Systemic Aspergillosis With Discospondylitis

Species:
dog

Plain-English summary

An 8-year-old spayed female German Shepherd was brought in with neck pain, difficulty walking, and lameness in her left front leg that had been worsening over two weeks. Tests revealed she had a rare fungal infection caused by an unusual strain of Aspergillus floccosus, which was linked to her spinal issues. The veterinarian started antifungal treatment, which is crucial for managing this type of infection, even when symptoms seem mild. With the right therapy, the dog can improve and avoid serious complications.

Abstract

ABSTRACT Disseminated aspergillosis is uncommon in dogs and typically caused by Aspergillus terreus. This report describes a systemic aspergillosis linked to discospondylitis in an 8‐year‐old spayed female German Shepherd presented with a 2‐week history of neck pain, progressive proprioceptive ataxia and ambulatory paraparesis and lameness of the left front limb. For the first time, an atypical strain of Aspergillus floccosus, section Terrei, was identified by culture and molecular methods. This finding emphasises the importance of molecular biology in fungal species identification, which is essential for accurate diagnosis and appropriate treatment. Our report further highlights that fungal infections should always be considered in German Shepherds with neurological signs, and the importance of maintaining antifungal therapy even in patients with few or no clinical or laboratory signs of active infection to prevent deterioration and death.
