Abstract
The distribution and morphological features of bronchus associated lymphoid tissue (BALT) were evaluated in three months old calves. Five types of lymphoid tissue were found but their distribution varied between regions and individuals. Scattered lymphoid cells were most predominant form. Dense lymphoid aggregates were frequently seen in bronchioles. Follicular lymphoid tissues were seen in bronchi. Small numbers of intraepithelial lymphoid cells were always located throughout the epithelium of mucosa. The intraluminal lymphocytes were observed mainly in bronchi and large bronchioles. The follicular development of BALT was less frequent and only occurred in the large bronchi of anterior cranial lobe in calves 3. The lymphoepithelium invagination of bronchi can be found in calve 1 as in that of duodenum of gut. The occurrence and morphology of BALT were different within the individual.
