Chronic bronchitis in horses
Every horse coughs once in a while. But most horses who regularly have some or more coughing have chronic bronchitis. A respiratory tract stimulates the airways mucosa to secrete more mucus. This mucus is sent to the throat and horse coughing is caused by creaking of the mucus. Chronic bronchitis can be the result of a "normal" respiratory infection caused by a virus or a bacterium. An inflammation lasting longer than a few weeks is called chronic.
It seems logical to think that only horses in a dusty stable can suffer from this, but that's not true. Horses can become more sensitive to dust due to hereditary construction or infection of the respiratory tract.
