Tracheobronchial aspirates were obtained by bronchoscope from 29 two-year-old Thoroughbreds immediately after long-distance transportation for examination for cells and bacteria. A number of neutrophils were observed in the aspirates of 6 horses, and a number of different bacteria were isolated from most of the horses. Five of the 6 horses (83.3%) with numerous neutrophils showed a marked increase in rectal temperature (≥39.0°C) or peripheral leukocyte count (≥15,000 cells/µl) immediately after

Results of this study indicate that measurement of rectum temperature and peripheral leukocyte counts after transportation can be used as a practical index for diagnosis of respiratory infectious disease associated with transportation.
