Pro§ek F., K. Heili~ek: Serological Examination and Demonstration of Toxo­ plasma gondii in Slaughter Pigs. Acta vet. Bmo, 50, 1981: 229-232. Over a 12-month period of 1979 and 1980 examined were 432 slaughter pigs, viz. serologically using the Sabin-Feldman reaction (SFR), using microprecipitation in agar gel (MPA) and an isolation biological experiment on toxoplasma-negative white mice. In the animals examined SFR and MPA were positive in 9.25 % and 0.46 %, resp. T. gondii was isolated from the brain or diaphragm of 14 animals, i. e. 3.24 % of the total number of 432 animals examined and 35 % of SFR positive animals. The highest occurrence of T. gondii was found in pigs slaughtered in November followed by those slaughtered in June. Toxoplasmosis, pigs, causative agent, occurrence of antibodies.
