The present study included 8 mares of the Tinker breed with clinic of Recurrent airway obstruction (RAO), characterized by difficulty breathing, coughing, rapid fatigue during exercise. No changes in body temperature and heart rate were found. There were no abnormalities in erythrocyte count, erythrocyte indices, hemoglobin, hematocrit, platelets, leukocytes and differential blood count. Tracheal endoscopy revealed an accumulation of increased mucus (grade 3-5), edema of the tracheal bifurcation, and spasm of the main bronchi. The following microorganisms were isolated in tracheal lavage (TW): Streptococcus equi, subsp. zooepidemicus (2 horses), Streptococcus pneumoniae (1 horse), Pasteurella spp. (1 horse), Klebsiella pneumoniae (1 horse) and Pseudomonas aeruginosa (1 horse). Cytological examination of tracheal specimens revealed mainly neutrophil leukocytes. The other cells observed (macrophages and lymphocytes) were in a significantly lower percentage.
