Abstract
Ten 75-105 day pregnant does each were inoculated orally with 1 million (2 does), 10,000 (4 does) or 1000 (4 does) sporocysts of Sarcocystis from coyote feces. Two does not inoculated with sporocysts served as controls. The 2 does inoculated with 1 million sporocysts died from acute sarcocystosis 21 and 22 days after inoculation (DAI) and each had 2 dead fetuses. The 4 does inoculated with 10,000 sporocysts were ill 19-33 DAI but survived; one aborted at 33 DAI, one had a live kid that died within 2 h of birth 31 DAI, one aborted 2 dead fetuses 23 DAI and one had a normal kid 56 DAI. The 4 does inoculated with 1000 sporocysts and the 2 control does remained clinically normal and had normal kids. Does and their offspring were killed within 24 h of parturition and their tissues examined histologically and microbiologically. Meronts of Sarcocystis were found in the maternal placenta of does inocualated with 1 million sporocysts. Sarcocystis was not found in the placenta, fetuses or tissues of kids from does inoculated with 10,000 or 1000 sporocysts or from control does. Other abortifacient agents were not found in the placenta, fetuses or kids from any does.
