[Immunologic status in cattle naturally infected with the microorganisms Chlamydia trachomatis and Chlamydia psittaci].
In the present paper there is a description of immunological reactions in 12 to 14 months old bullocks, naturally infected by the microorganisms Chlamydia (Ch.) psittaci and Chlamydia trachomatis. In the course of infection by the above-mentioned microorganisms (chlamydia isolated from semen) without any clinical symptoms the activity of leucocytes and polymorphonuclear cells (PMN) in the peripheral blood is variable and the concentrations of serum immunoglobulins (IG) decrease. It has been demonstrated that the infection of bullocks by Ch. trachomatis increases the bacteria absorbing capacity of PMN cells (from 14.2 to 20.1), percent of phagocytic cells in the peripheral blood (from 13.0 to 26.5%). NBT reduction activity both in a spontaneous test (from 3 to 6) and in a stimulated test (from 8 to 12), and also myeloperoxidase activity (from 0.29 to 0.42). In these animals there were also recorded decreases (although not statistically significant) in the concentrations of serum IgG1, IgG2, IgA by about 10% and by about 30% in IgM. In Ch. psittaci-infected bulls leucocyte migration in the peripheral blood decreased (from 4.5 to 2.7 mm). PMN cell adherence (from 50 to 32), lysosome amount (from 0.63 to 0.35 mg per l) also decreased. In these bullocks decreases in the concentrations of serum Ig from 12.2 to 8.2 g per l in IgG1 and from 3.8 to 1.7 g per l in IgM were also proved.
