Blastomycosis (Blastomyces spp.)
Infectious DiseaseFungusCanineNew
Key Points
  • Blastomycosis is a systemic fungal disease, caused by Blastomyces spp.
  • While the lungs are most often affected, infection can disseminate throughout the body and affect other organs (e.g. skin, bones, lymph nodes, eyes, CNS)
  • Clinical signs vary depending on the affected organs but commonly include pyrexia, weight loss, dyspnoea, lethargy and cough
  • Cytology and histopathology are best for diagnosis as they directly identify the organism
  • Itraconazole is the most commonly used antifungal but amphotericin B is often used in more severe cases
  • Prevention focuses on preventing exposure to Blastomyces spp.
