Prevalence of Sarcocystis in sows from Iowa.
The hearts of 893 sows from Iowa killed for food between January 1990 and February 1992 were examined for Sarcocystis bradyzoites by the digestion technique. Bradyzoites were found in 163 (18.2%) hearts. Sections of formalin-fixed tissues from 28 hearts with demonstrable bradyzoites were examined for sarcocysts. Sarcocystis miescheriana sarcocysts were found in six pigs. The prevalence of Sarcocystis was apparently not affected by season.
