The occurrence of antibodies against Toxoplasma gondii and of T. gondii itself were monitored in pigs in the district of Strakonice in South Bohemia (Czech Republic) during 1979-1990. A total number of 2,635 slaughter pigs were examined. The antibodies were found in 5.9 % out of 2,616 samples by Sabin-Feldman test (SFT, titre/-4), in 0.3 % out of 1,179 samples by complement fization test (CFT, titre/-10), and in 0.1 % out of 2,306 samples by microprecipitation in agar gel (MPA). T. gondii was demonstrated in 1.6 % out of the total number of 2,447 examined animals. Altogether 57 pigs, which were slaughtered out of the slaughterhouse, were examined, and the antibodies were found in 35.1 % (SFT), and 14.0 % (CFT). T. gondii was detected in 10.2 % of the pigs. Samples of blood serum were examined in 230 pigs in 10 small-scale farms. The antibodies were detected in 30.9 % (SFT; out of 230 examined animals), in 9.5 % (CFT; out of 158 examined animals), and in 0.5 % (MPA; out of 202 examined animals). Most positive cases were found both by serological tests and by isolation of the parasite in the pigs from small-scale farms. There were smaller numbers of positive cases from large-scale farms with old technology, and the lowest number of positive cases was found in the pigs from modern large-scale farms.
