Pregnancy-associated glycoprotein levels in pregnant goats inoculated withToxoplasma gondii or Listeria monocytogenes: A retrospective study

The pregnancy-associated glycoprotein (PAG) concentration profiles of goats that had been experimentally inoculated with either Toxoplasma gondii or L isteria monocytopenes are described. All goats were examined regularly by u ltrasonography. In T. gondii-infected females (n=5), a slow decrease of PAG was observed throughout a period of 55 to 74 d after inoculation. Afterwar ds, the goats either aborted (n=4) or kidded 1 dead and 1 weak fetus (n=1). In L. monocytogenes-infected females (n=8), a marked decrease of PAG was o bserved from the day of inoculation. Abortion occurred within 9 to Il d pos t inoculation (n=7). Only I goat kidded a healthy fetus.
