The aim of the study was to investigate the induction of autoantibodies in rabbits after the inoculation with Trypanosoma equiperdum. Eight female rabbits were inoculated s.c. with 5 x 10(6) parasites of Trypanosoma equiperdum. Four of these animals were treated with Diminazen (Berenil) at a dosage of 28 mg per rabbit by intramuscular injection 35 days p. i. Two additional non-infected rabbits served as negative controls. 9 days p.i. all infected animals possessed serum antibodies against Typanosoma equiperdum. Titers peaked to 1:2048, measured between 14 and 30 days p.i. and were persistent until the end of examinations. In parallel, there was an increase of anti-dsDNA and anti-collagen autoantibodies, but not of autoantibodies against recombinant U1RNP and La antigens. In comparison to patients with systemic lupus erythematosus, the anti-DNA binding of rabbit's sera was reduced more strongly in presence of increasing salt concentrations. In addition, the sera of inoculated rabbits recognized several unknown bands of a cell extract in immunoblotting. The parallel increase of antibodies against Trypanosoma, control foreign antigens, DNA and collagen suggests a polyclonal stimulation of the immune system. It was concluded that this rabbit model seems to be sufficient to investigate the mechanisms which are able to induce autoimmune phenomena.
