Contribution to the biology of experimental Sarcocystis suicanis infection in domestic swine


, : Contribution to the biology of experimental Sarcocystis suicanis infection in domestic swine. Dissertation Abstracts International, B Sciences and Engineering 47(8): 3266

Electron microscopy of the sporocyst wall of S. suicanis showed that it was composed of four plates which separate at their margins when exposed to excysting fluids. The resulting gaps allow sporozoites to escape. Three pregnant sows infected with 2 million sporocysts aborted 11-12 days after infection. Increases of PGF-M and TX-B2, the stable metabolites of prostaglandin F2 alpha and thromboxane A2, respectively, occurred immediately prior to abortion.

Titres did not fall much during the obs...
