title: Scanning electron microscopy of the tracheal epithelium of calves inoculated with bovine herpesvirus 1.
abstract: Tracheal epithelium was examined by light, scanning electron and transmission electron microscopy at four, five and seven days after calves were infected intranasally with bovine herpesvirus. Similar areas were examined from uninoculated calves. Tracheal epithelial lesions were found in all inoculated calves and their degree of severity did not vary with the interval between inoculation and examination. Extensive loss of cilia leaving areas of tracheal epithelium covered by microvilli was the main feature.
