Abstract
The nine-banded armadillo (
Dasypus novemcinctus) is an intermediate host of at least three species of
Sarcocystis,
Sarcocystis dasypi,
Sarcocystis
diminuta, and an unidentified species; however, life cycles of these species have not been determined. Following feeding of armadillo muscles containing sarcocysts to the Virginia opossum (
Didelphis virginiana), the opossums shed sporulated
Sarcocystis sporocysts in their faeces. Mean dimensions for sporocysts were 11.0×7.5 μm and each contained four sporozoites and a residual body. Sporocysts were identified as
Sarcocystis neurona using PCR and DNA sequencing. A 2-month-old foal that was negative for
S. neurona antibodies in the CSF was orally inoculated with 5×10
5 sporocysts. At 4 weeks post-infection, the foal had a ‘low positive’ result by immunoblot for CSF antibodies to
S. neurona and by week 6 had a ‘strong positive’ CSF result and developed an abnormal gait with proprioceptive deficits and ataxia in all four limbs. Based on the results of this study, the nine-banded armadillo is an intermediate host of
S. neurona.
