Scanning electron microscopy of Sarcocystis fusiformis from the water buffalo (Bubalus bubalis).

Scanning electron microscopy of Sarcocystis fusiformis from the water buffalo (Bubalus bubalis) reveals the presence of two cyst walls and distinct compartments within the cyst. Merozoites lie in large numbers in each compartment and in some cases are covered by a membrane-like exudate. Each merozoite has a micropore situated in the anterior half and ridge-like structures originate from the conoidal end and pass backwards along the body of the parasite.
