===Clinical Signs===
===Clinical Signs===
Generally, the first clinical signs reported by an owner are
occasional coughing and exercise intolerance. As disease severity progresses, the cough becomes more frequent
and severely affected horses will have paroxysmal bouts
of coughing. Horses are typically afebrile, but have a progressively
elevated respiratory rate and varying amounts of
mucopurulent nasal discharge. In severe cases, signs of respiratory
distress (eg, flaring of the nostrils, audible wheezing
at the nostrils and obvious abdominal expiratory effort)
are apparent at rest. Horses that are markedly dyspnoeic
may not maintain body condition due to increased energy
expenditure caused by the increased work of breathing.
In chronic severe cases, a ‘heave’ line may develop due to
hypertrophy of the external abdominal oblique muscle.
