Which disease affects the turbinate bones in swine?

1. Atrophic rhinitis

2. Porcine pleuropneumonia

3. Swine influenza

4. Transmissible gastroenteritis

The correct answer is: Atrophic rhinitis

Atrophic rhinitis is a significant respiratory condition in swine that specifically affects the turbinate bones, which are the bone structures in the nasal cavity that help filter and warm the air the animal inhales. This disease is characterized by inflammation and atrophy of these bones, leading to facial deformities and respiratory difficulties. The causative agents are often bacteria, which can lead to changes in the structure of the turbinate bones, making atrophic rhinitis unique among the listed diseases in its specific impact on the nasal anatomy. In contrast, porcine pleuropneumonia primarily affects the lungs and pleura and can lead to serious respiratory issues but does not specifically damage the turbinate bones. Swine influenza, while also a respiratory disease affecting pigs, does not have a direct impact on the structure of the turbinate bones in the same manner. Transmissible gastroenteritis primarily affects the gastrointestinal tract, causing severe diarrhea and dehydration in young pigs without involving respiratory anatomical features. This specificity to the turbinate bones is what makes atrophic rhinitis the correct answer in this context.
