ATYPICAL BASAL BODIES IN A NORMAL, APPARENTLY HEALTHY COW

The authors report an altered geometrical configuration of some basal body cylinder in a normal, apparently healthy cow. Defective basal bod ies of the so-called 'half-centriole' are described. Only one microtub ular pattern is composed of ten triplets encircling an apparently symm etric lumen. In medical literature there are a few documented cases of basal body cylinder defects. Most of them have been described in cili ary pathology. This paper deals with the first cases of basal body abn ormalities observed in a healthy domestic animal.
