The aim of the report was to compare the cytology and phagocytosis of the cells obtained in tracheobronchial aspirate (TBA) and bronchoalveolar lavage (BAL). Expirements were performed on 15 normal horses, 428±62 kg b.w. TBA and BAL were collected with bronehofiberoscope and sterile non pyrogenic buffered saline, 37°C. The seperated cells were counted, their total number and picture were estimated. Two standard bacterial strains S. aureus Smith and 305 were used to determine phagocytic activity of neutrophiles and macrophages. Neutrophile phagocytic activity in pheripheral blood of the same horses was also estimated. Result show significant differences in the percentage of neutrophiles isolated from TBA and BAL. There were no significant changes in the phagocytic activity of cells in TBA and BAL. Experiments revealed significantly decreased neutrophile phagocytosis in peripheral blood compared to cells from TBA and BAL.
