SARCOCYSTIS-DUBEYELLA N. SP. AND SARCOCYSTIS-PHACOCHOERI N. SP. (PROTOZOA, SARCOCYSTIDAE) FROM THE WARTHOG (PHACOCHOERUS-AETHIOPICUS) IN SOUTH-AFRICA

Sarcocystis dubeyella n. sp. and S. phacochoeri n. sp. from muscle fib ers of the skeletal musculature of two warthogs in South Africa are de scribed by light and and electron microscopy. Sarcocystis dubeyella sa rcocysts are macroscopic (up to 12 mm long and 1 mm wide), with a para site-induced encapsulation of the host muscle fiber in which the plasm a membrane of the latter remained unaltered. The sarcocyst wall is cha racterized by evenly arranged, irregularly semicircular or rectangular villar protrusions (5.0 x 2.8-11.0 mu m) with indented margins and no specific content. Sarcocystis phacochoeri formed filiform microcysts (up to 4 mm long and 0.13 mm wide). Its cyst wall is provided with tig htly packed, molarlike villar protrusions (1.6-3.3 x 1.7-3.3 mu m), wi th smooth margins, hollow on one side, and with longitudinal condensat ions of the fine granular matrix at various locations in the interior.
