What is Aspergillosis?

Aspergillosis is an often fatal disease that primarily impacts raptors, caused by the growth of the fungus Aspergillus in the respiratory system. This fungal infection can lead to severe respiratory issues, as the spores of Aspergillus can be inhaled, particularly in environments where the fungus proliferates, such as in damp or moldy conditions. In birds of prey, the disease can result in significant health complications, including difficulty breathing, decreased appetite, and ultimately, if left untreated, death.

In understanding the nature of Aspergillosis, it's clear that it is not caused by a virus, which distinguishes it from options referring to viral infections. It also does not relate to parasites, which involve entirely different pathogens and disease mechanisms. Finally, it is unrelated to low blood sugar, which is a metabolic issue rather than a fungal infection affecting the respiratory system. Thus, recognizing Aspergillosis as a serious fungal disease is crucial in managing the health of raptors in falconry and wildlife rehabilitation settings.
