RESUMEN
The aim of the present study was to investigate the likelihood of transplacental transmission of Neospora hughesi and Sarcocystis neurona in foals, born from seropositive mares. Three broodmares with persistent N. hughesi infection gave birth to eight healthy foals over a period of 7 years. These foals were seropositive to N. hughesi prior to colostrum ingestion, with titers ranging between 640 and 20,480, measured by indirect fluorescence antibody test (IFAT). Of 174 foals born at another farm to mares with a high seroprevalence to S. neurona, only one (with a pre-colostrum antibody titer of 80) tested seropositive. Transplacental transmission of N. hughesi seems to occur from latently infected mares to their foals, while this route of transmission does not seem to occur commonly for S. neurona.

Experiments have established that the first target for echinococcus is the liver and lung and that for pathogenic fungi and protozoa is the heart. Adult patients with hepatic hydatid disease complicated by paecilomycosis have been found to have atypical paecilomycosis-associated myocarditis, the treatment of which was developed by the authors, by using antibiotics, fungicides, and homeopathic remedies.
