TL;DR: While the specificity of tongue palpation and meat inspection was 100%, these tests failed to detect the infection in 83.9% and 61.3% of infected pigs, respectively.

TL;DR: The present study shows that S. mattheei could induce placentome lesions and that eggs can cross the placenta, Consequently, foeti can come into contact with S. mattressheei antigens in utero, and might also contain maternal antibodies from leakage through placente lesions.

TL;DR: Colostral effects, which were noticed at an early age, are no longer present around the age of 7 months, and calves which are born during a season of high Schistosoma transmission will still be under colostral influence and therefore be more protected against a primary challenge than calves Born during a low transmission season, as the latter will only receive their first challenge when colostrals protective effects have disappeared.

TL;DR: The results indicate that the calves were primed against S. mattheei and might explain why seropositive-born calves from infected dams are better protected against the antigens, and query the impermeability of the damaged ruminant placenta with consequences for antigen transfer.
