title: [Accidental thymus involution in calves].
abstract: In 149 necropsied calves (age 0 to 28 days) a reduced thymus was found. The absolute thymus weights varied between 6 and 220 g. The relative thymus weights (applied to bodyweight) were between 0.02 and 0.52% (healthy controls 0.24 to 0.67%). The histological changes resemble those of accidental thymus involution. Corresponding to the duration of the disease and/or loss of body weight of the animals there is an increase of lymphocyte depletion. The accidental thymus involution is presumed to be a morphological expression of a secondary immunodeficiency.
