of RAO.
merck Bronchoalveolar lavage is rarely required for diagnosis of fulminant RAO, and is not innocuous in horses that are dyspneic at rest. It is indicated in horses with mild to moderate disease with poor performance and coughing during exercise. Neutrophilic inflammation (20-90% of total cell count) confirms the presence of lower airway inflammation and differentiates horses with eosinophilic pneumonitis, fungal pneumonia, or lungworm infestation from horses with heaves. Curschmann’s spirals may be observed on cytologic evaluation and represent inspissated mucus/cellular casts from obstructed small airways
