Fungal Infection (Blastomycosis) in Cats

ADVERTISEMENT

Treatment

 

Treatment is generally done at home using oral dosages of an antifungal medication. The medication is relatively expensive and must be administered for a minimum of 60 days, or one month after all signs of blastomycosis have disappeared.

 

In severely prolonged infections, or when medication has not cured the infection, surgery may be necessary to remove part of an abscessed lobe in damaged lungs. Chest X-rays can help determine the duration of and response to treatment, and reveal any permanent changes in the lungs that may have resulted from the treatment.

 

Living and Management

 

Even if your cat's health improves soon after starting medications, you will need to continue with the full course of antifungal medication to be positive that the infection will not recur. Limiting your cat's physical activities will also help in the recovery by avoiding excess strain on the lungs. Cage rest, or limiting your cat to an enclosed environment will encourage your cat to rest as much as possible. A high-quality diet to stimulate your cat's appetite is also encouraged during this time.

 

The disease is mainly spread through soil, but also has the possibility of being spread from animals to people through bite wounds. It should also be considered that you may have been exposed to the blastomyces organism at the same time as your pet. You will need to inform your own physician if you have breathing problems or skin lesions; both are possible indicators of blastomycosis.

 

Prevention

 

This condition often is acquired in environments where decaying wood is found: farms, forests, wooded areas, camps, hunting areas. Decay of other organic material is also conducive to its growth in soil, especially when the soil is not exposed to sunlight and remains damp all the time.

 

Conversely, the spores may be more likely to go airborne during dry weather, when the contaminated dust is lighter. It is not easy to predict exactly where the blastomyces organism may be growing, and is thus difficult to avoid entirely.

 

The only useful recommendation that can be given is to avoid lakes and streams where risk of exposure is greatest. This is, admittedly, an impractical suggestion for most. If you do live or spend time in these types of geographic areas, you may practicably be able to avoid the dense, dark areas where the fungus would thrive, reducing your pet's risk of exposure. As well, if your cat's immune system is already compromised, you will not want to include it in trips to high risk areas.

 

This condition is only rarely transmittable from animal to animal, or from animal to human. In the event that transmission does occur, it is when the animal has an open and draining wound, and it comes into contact with an open wound on the human, or the discharge from the animal's wound gets into the human's eye. Taking care to avoid these circumstances when caring for your pet will be sufficient prevention.
