The fungus produces spores, which if inhaled from the soil or dust can cause the infection. The disease cannot be transmitted from an infected animal to other animals or to people in most cases. Most animals that inhale the spores do not become infected, and many become resistant to infection. The other form, known as the disseminated form, can involve bone, joints, skin and other organ systems. This form is much more difficult to treat.
Diagnosis is made through blood tests, X-rays, biopsy, or other tests depending on areas affected.
Other treatments are available for more severe cases. Treatment is a slow process and may take over a year in some cases. Follow-up testing is required to monitor the success of the therapy. This testing is extremely important if your pet is to be cured. Some pets with the disseminated form may not be cured, although long term therapy may control the illness in many cases.
