摘要: Vostalova E., I. Literak, Pavlasek, K. Sedlak: Prevalence of Toxoplasma gondii in Finishing Pigs a Large-scale Farm the Czech. Acta Vet. Brno 1999, 69: 209–212. In January, April and November slaughter pigs from large-scale farm South Bohemia, Czech Republic, were tested for antibodies assayed T. gondii. The complement fixation test (CFT) revealed 4 787 (0.5%). Sabin-Feldman (SFT) 259 1 pig (0.4%). two tests, titres 8 respectively considered positive. An isolation biological assay on laboratory mice was used to tissue specimens brain diaphragm muscles 97 randomly selected tests. results tests negative. showed that between 1981-1990 no significant toxoplasmosis seroprevalence changes occurred this modern characterized by high standard zoohygiene veterinary supervision. Pigs, gondii, antibodies, Swine is world-wide infection caused an intracellular parasite, pigs, latent form disease usually develops, but clinical cases have also been reported (Dubey B eattie 1988). real problem lies fact tissues infected animals may contain cysts these, if ingested insufficiently cooked pork personal hygiene principles poor when cooking it, cause or even infections man (Jira R osick˘ 1983). Pig has given particular attention countries where plays important role human diet. several studies made recent decades. serological 1948-1970 period summarized Kouba et al. (1974). period, among 37.5 %, 41.9 % 10.7 as ascertained (SFT), microprecipitation agar gel (MPA), respectively. Another study 1979 1989. average 8.8% (Hejliaek Literak 1993). most extensive 1990. It looked into prevalence Bohemian district Strakonice (He jliaek Antibodies against found 5.9%, 0.3% 0.1% SFT, CFT MPA examined came farms offered possibility comparison. marked decrease 1979-1990 comparison with 1948 - 1970 period. highest small backyard operations, while traditional large more so lower.
