Shepherd dogs (276), males, at the age of ca. 1 year, from various regions of Poland, were examined. The complement fixation test with the antigen obtained from the exudate of infected mice and intracutaneous test (0.1 ml of toxoplasmine 1:100-1:1000, reading after 24-28 hours, control test with spleen exudate from healthy mice) were performed paralelly. A positive result of both tests was obtained in 10 dogs (4%): in 52 dogs (19%) it was found to occur only with the romplement fixation (titre 1:3-1:8) and in 30 ones (11%) only with the intracutaneous test.
