What is a common source of infection for aspergillosis in birds?

1. Water contamination

2. Fungus-contaminated bedding

3. Direct contact with sick animals

4. Ingestion of infected food

The correct answer is: Fungus-contaminated bedding

Aspergillosis is a fungal disease caused by the Aspergillus species, and in birds, a prevalent source of infection is indeed fungus-contaminated bedding. This is especially relevant in environments where birds are housed, as a damp or dirty bedding material can promote the growth of Aspergillus spores. When birds are exposed to these spores—often present in organic material like straw, hay, or wood shavings—they can inhale the spores, leading to respiratory infections. The link between contaminated bedding and aspergillosis is significant, especially in confined or poorly ventilated spaces, where the accumulation of fungal spores can be higher. Birds are particularly susceptible due to their respiratory systems, which can be compromised by stress or underlying health issues, making them more likely to develop infections following exposure. Understanding this mode of transmission is crucial for wildlife rehabilitators to implement effective preventive measures in avian care.
