What type of infection arises from warm, moist environments and commonly affects raptors?

Aspergillosis is a fungal infection that commonly affects raptors and is particularly associated with warm, moist environments. This condition is caused by the Aspergillus species of fungi, which thrive in such conditions and can lead to severe respiratory issues when inhaled. Raptors, especially those in captivity or in environments where humidity and temperature are not adequately controlled, are at a higher risk. The spores of Aspergillus are often found in organic materials, including bedding, feed, and even decaying plant matter, making it essential for falconers to maintain a clean and dry habitat for their birds to minimize risk.

The other infections mentioned, while they may also impact birds, arise from different sources and conditions. Salmonella is a bacterial infection that can result from contaminated food or water, Ascarids are intestinal parasites that can affect various bird species, and Coccidiosis is a protist infection that typically occurs in wet environments but is less specific to temperature and moisture levels compared to Aspergillosis. Thus, understanding the specific environmental needs and risks associated with Aspergillosis makes it clear why it is the correct answer to this question.
