Aspergillosis in Cats

Aspergillosis is a fungal infection in cats. Aspergillosis is an opportunistic fungal infection caused by the Aspergillus, a species of common mold found throughout the environment, including dust, straw, grass clippings, and hay. An opportunistic infection occurs when an organism which does not generally cause disease becomes an infectious agent once it has entered into an animals body. In the case of Aspergillosis, it becomes an infectious agent when the body's immune system is weakened from some other disease or illness.

There are two types of acquired Aspergillus infection: nasal and disseminated. Both types can affect cats, and while no particular breed is more prone than another, Persians show a slightly higher incidence.

Symptoms and Types

There are two types of Aspergillus infections. The first is the nasal form, where the infection is localized in the nasal passages and front sinuses. It is believed that this develops from direct nasal contact with the fungus. For example, if a cat is outside and around dust and grass clippings, the fungus may enter via the moist lining of the nose. The most commonly associated symptoms are nasal discharge and noisy breathing during inhaling.

The second type of Aspergillus infection is disseminated, meaning it is more widespread in the body, not only in the nasal area. It is not certain how this form enters the body. Disseminated aspergillosis is most commonly associated with nonspecific signs, such as lethargy, depression, vomiting, and diarrhea. Other symptoms may include protruding eyeballs.

Our Kiki was diagnosed with this disease by two different vets last year. They ran the necessary blood tests and performed a sinus endoscopy so they could get a biopsy sample to be sure and they also cleaned her sinus passages out as well. 

While there is no cure for this type of infection, the only thing we can give her is some meds on a daily basis to help make her comfortable. She has been eating good and as long as she is doing so and showing no other problematic symptoms, we will help her to fight this issue.
