Detection of Sarcocystis neurona Antibodies in the Serum and CSF of Foals

摘要

Maternal antibodies to Sarcocystis neurona are passively transferred from a seropositive mare to her foal in colostrum and can remain detectable by Western blot for up to 9 months of age, although most foals are seronegative by 6 months of age. Antibodies are detectable in CSF of neonatal foals from several days to age up to at least 3 months of age.
