Abstract

Isolated cysts ofSarcocystis aucheniae of the llama (Lama glama) were fed to one dog and one cat. Only the dog excreted sporocysts, measuring 13.1–15.7 (15.0±0.54)×9.0–11.3 (10.4±0.36) μm after 11 days for 21 days. A second cat, which had ingested meat of a llama containing macrocysts ofS. aucheniae as well as sarcosporidial cysts visible only under a microscope also did not excrete sporocysts. The cysts ofS. aucheniae are surrounded by a folded primary cyst wall forming cauliflower-like protrusions into the muscle fibre. The protrusions contain numerous microfilaments. In addition, the primary cyst wall forms numerous tiny vesicles. The parasitized muscle fibre is located in a large cavity within the normal muscle tissue. The cyst wall ofS. aucheniae is similarly structured to that ofS. gigantea of the sheep.

Zusammenfassung

Isolierte Zysten vonSarcocystis aucheniae aus dem Lama (Lama glama) wurden an einen Hund und an eine Katze verfüttert. Nur der Hund schied nach 11 Tagen für 21 Tage 13,1–15,7 (15,0±0,54)×9,0–11,3 (10,4±0,36) μm große Sporozysten aus. Eine zweite Katze, die Lamafleisch erhalten hatte, das sowohl Makrozysten vonS. aucheniae als auch nur mikroskopisch sichtbare Zysten enthielt, blieb ebenfalls negativ. Die Zysten vonS. aucheniae sind von einer Primärhülle umgeben, die blumenkohlartige gefaltete Vorwölbungen in die sie umgebende Muskelfaser bildet. Die Vorwölbungen enthalten zahlreiche Mikrofilamente. Die Primärhülle besitzt außerdem viele sehr kleine bläschenförmige Einstülpungen. Die parasitierte Muskelfaser liegt in einem großen Hohlraum im normalen Muskelgewebe. Die Zystenwand vonS. aucheniae ist ähnlich strukturiert wie die vonS. gigantea des Schafes.
