Prevalence and identity of Sarcocystis infections in armadillos (Dasypus novemcinctus).
Little is known about the prevalence or identity of Sarcocystis species infecting armadillos in North America. Sarcocysts were observed in the tongues of 23 (96%) of 24 armadillos collected between 1989 and 1994 from Texas, Oklahoma, Kansas, and Arkansas. The identity of the species present was determined in histological sections of tongue from armadillos. Sarcocystis dasypi was present in 21 (88%) and Sarcocystis diminuta was present in 5 (21%). Mixed infections with S. dasypi and S. diminuta were present in 3 (13%) armadillos. A single sarcocyst with ultrastructural features distinct from S. dasypi and S. diminuta was observed with transmission electron microscopy.
