Abstract:
:Macroscopically visible sarcocysts were observed in the skeletal muscles of naturally infected skinks of the genus Agama (infection rate 11.3%). Sarcocysts were described by means of transmission electron microscopy. These cysts measured 0.03-0.25 x 0.38-1.7 mm (mean 0.12 x 1.1 mm). Typical mature cysts were bordered by a primary cyst wall that measured 2.4-5.3 microm (mean 3.9 microm) and was folded into a few nonbranched finger-like protrusions measuring 0.7-1.5 x 1.0-2.5 microm (mean 1.2 x 1.5 microm). These protrusions contained granular elements, but filaments and tubular elements were not observed. A relatively thick, homogeneous tape was observed just underneath the primary cyst wall, measuring 0.5-1.0 microm (mean 0.8 microm) and containing a granulated ground substance in which filaments and tubular elements were not observed. Metrocytes measured 3.1-5.5 x 4.2-7.2 microm (mean 4.0 x 5.8 microm) and merozoites measured 1.2-3.3 x 4.4-8.6microm (mean 2.6 x 7.5 microm). The fine ultrastructural characteristics of both metrocytes and merozoites were similar to those described for many Sarcocystis species and were generally nonspecific.
