What is a common consequence of low ammonia levels in rabbit enclosures?

Low ammonia levels in rabbit enclosures are often associated with improved air quality, which is crucial for the health of rabbits. High ammonia levels can lead to respiratory issues and infections, especially in the presence of other pathogens. Pasteurellosis, caused by the bacterium Pasteurella multocida, is a respiratory disease that can be exacerbated in poor air quality conditions where ammonia levels are elevated. Therefore, maintaining low ammonia levels helps reduce the risk of this infection, making the connection to Pasteurellosis very relevant.

In contrast, the other conditions mentioned are not directly linked to ammonia levels in the same manner. Bordetellosis, while also a respiratory disease, is typically caused by a different pathogen and is less influenced by ammonia. Fleas and ear mites are external parasites and are not related to ammonia levels, but rather depend on factors like hygiene and environment.
