title: [Part played by bovine adenoviruses in calf diseases].
abstract: Parallel investigations were carried out on twice obtained blood serum samples (at 15-20 day intervals) from a total of 176 affected calves, exhibiting  a respiratory syndrome on 20 cattle breeding farms, with the use of the immunodiffusion test with antigens obtained from prototypic strains of B-10 and Misk/67 bovine adenoviruses (1st serotype for 1st subgroup and 8h serotype for 2nd subgroup). In 16 out of 20 recorded enzootics adenoviruses participated in a varying degree in the etiology of the disease. In 23.28 per cent of the diseases calves there were newly appearing antibodies against the group-specific adenovirus antigens. In 14.20 per cent of the animals the antibodies were against 1st antigen subgroup, and in 9.03 per cent of them the antibodies were against the antigen of the 2nd subgroup. In 6 of the enzootics the relative share of adenoviruses was shown to be considerable (up to 40 per cent), and in 11 of them their participation was only partial.
