Allergometric examinations were performed in 50 dogs reacting positively with toxoplasmine. The types of the obtained reactions were: pleoergic (6.7%), homodynamic (40%), and pleoesthetic (53.3%). Its is believed that the reason for a comparatively high frequency of pleoesthesis is to be searched in breeding conditions and care of dogs. In the group of animals kept in azylum, fed on fall offs and slaughter confiscates, positive Sabin-Feldman reaction occurred in 17.9% of dogs. A similar, high percentage (18.8%) of positive serologic reactions was detected in 101 rural dogs, whereas among 153 race dogs belonging to members of Kynologic Society they were found only in 8.3%.
