A comparison was made of the cellular and molecular components of bronchoalveolar lavage fluid (BALF) harvested from the left and right diaphragmatic lobes, the accessory lobe of the right lung and the apical lobe of the left lung, of seven control horses and six horses with symptomatic chronic obstructive pulmonary disease (COPD). Neither control nor symptomatic COPD affected horses showed significant regional differences in BALF recovery volumes, total and differential BALF cell counts, albumen adjusted total and absolute BALF cell counts, total and absolute pulmonary epithelial lining fluid (PELF) cell counts, and BALF albumen and urea concentrations. This suggests that the composition of PELF is uniform throughout the lungs of normal horses and horses with symptomatic COPD and that a single BALF sample is representative o the entire lung in these horses.
