Aspergillus versicolor, a new causative agent of canine disseminated aspergillosis.

Disseminated aspergillosis in dogs has been associated with Aspergillus terreus or A. deflectus infection. We report a case of disseminated A. versicolor infection presenting as diskospondylitis, osteomyelitis, and pyelonephritis. The diagnosis was made based on clinical, radiographic, and pathological findings. The etiologic agent was identified by fungal culture and internal transcribed spacer (ITS) ribosomal DNA (rDNA) sequencing. This is the first description of canine aspergillosis caused by A. versicolor.
