Primary inoculation blastomycosis in a veterinarian

Area of Science:

• Veterinary Pathology
• Mycology
• Infectious Diseases

Background:

• Blastomycosis is a fungal infection caused by Blastomyces dermatitidis.
• Exposure typically occurs through inhalation of spores.
• Canine blastomycosis is endemic in certain regions.

Observation:

• A veterinarian sustained a finger injury during a dog autopsy.
• The dog was diagnosed with blastomycosis.
• A chancriform lesion developed at the veterinarian's inoculation site.

Findings:

• Blastomyces dermatitidis was cultured from the veterinarian's lesion.
• The lesion healed after seven months of potassium iodide treatment.
• This represents the first documented case of primary inoculation blastomycosis in a veterinarian from a canine necropsy.

Implications:

• Veterinary professionals must exercise caution during animal autopsies, especially with suspected fungal infections.
• Accurate diagnostic procedures are crucial for identifying zoonotic potential.
• This case underscores the importance of biosafety protocols in veterinary practice.
