Prevalence of Sarcocystis sarcocysts in nine-banded armadillos (Dasypus novemcinctus) from Florida.
The prevalence and identity of Sarcocystis spp. sarcocysts in the skeletal muscles of nine-banded armadillos (Dasypus novemcinctus) collected from Alachua County, FL, were determined. H & E stained sections of skeletal muscle from tongue and thigh were examined. Thirty nine of 63 (61.9%) armadillos examined contained Sarcocystis sarcocysts. Two species were identified, Sarcocystis dasypi and Sarcocystis diminuta. Sarcocystis dasypi sarcocysts were found in 38 of 63 (60.3%) and S. diminuta sarcocysts were found in 6 of 63 (9.5%). Sarcocysts of S. dasypi were larger, more densely packed with bradyzoites, and bradyzoites contained within the sarcocyst were smaller than those of S. diminuta. Mixed infections occurred in 5 of 63 (7.9%) armadillos examined.
