Diagnosis of transplacentally induced toxoplasmosis in pigs.

摘要: Seventeen sows were fed 1,000 Toxoplasma gondii oocysts of isolates GT-1 or PT-1 at 32 to 92 days gestation, and the products conception examined for T antibodies parasites. Twelve these euthanatized near term between 21 62 after being gondii; fetal body fluids sera agglutinating antibodies, tissues bioassayed in mice Six produced pigs that had been transplacentally infected with one them aborted a gondii-infected fetus 17 ingesting oocytes. Agglutinating detected fetuses utero, but transplacental transfer was not observed noninfected fetuses. Transcolostrally acquired disappeared by 3 months age. Diagnosis toxoplasmosis confirmed on basis detection organisms use histologic examination bioassay mice. In conclusion, finding could serve as rapid screening test infection pigs.
