Overview:

Blastomycosis is a serious fungal infection that affects dogs, caused by the fungus Blastomyces dermatitidis. This infection primarily targets the lungs but can spread to other organs such as the skin, bones, and eyes. It is commonly found in certain geographical areas with moist, sandy soils.

Symptoms:

  • Respiratory Symptoms: Coughing, difficulty breathing, and nasal discharge.
  • Systemic Symptoms: Fever, lethargy, loss of appetite, and weight loss.
  • Skin Lesions: Unusual skin growths or ulcers.
  • Bone and Joint Issues: Lameness or pain.
  • Ocular Signs: Eye redness, discharge, or vision changes.

Diagnosis:

Diagnosing blastomycosis involves a combination of clinical signs, history, and laboratory tests. Veterinarians typically use:

  • Blood Tests: To check for abnormal levels of white blood cells or specific antibodies.
  • Radiographs (X-rays): To identify lung changes or other affected organs.
  • Fungal Cultures: To confirm the presence of Blastomyces dermatitidis.
  • Biopsy: To examine affected tissues under a microscope.

Treatment:

Treatment for blastomycosis often requires long-term antifungal medication. Commonly prescribed drugs include:

  • Itraconazole or Fluconazole: These antifungals help eliminate the infection.
  • Supportive Care: May include medications to manage symptoms such as pain or inflammation.

Treatment duration can range from several months to over a year, depending on the severity of the infection and the response to medication.

Prevention:

Preventing blastomycosis involves minimizing exposure to environments where the fungus is common. While it’s challenging to completely avoid such exposure, reducing your dog’s contact with moist, sandy soils and avoiding areas known for fungal outbreaks can help.

When to Seek Veterinary Care:

If you notice symptoms of blastomycosis in your dog or if your pet has been in areas where this fungus is prevalent, seek immediate veterinary attention. Early diagnosis and treatment are crucial for a better prognosis.
