Abstract
Estradiol, progesterone and hydrocortisone were measured by radioimmunoassay in peripheral serum of pregnant ewes infected with L. monocytogenes type 5 and in normal pregnant controls. Progesterone decreased in both groups at abortion or parturition. Estradiol and hydrocortisone of control ewes increased at parturition. In infected ewes, the serum hydrocortisone value was high for 3 days after inoculation, but it returned to preinoculation levels for the remainder of gestation. Serum concentrations of hydrocortisone did not change, and estradiol values increased slightly at abortion by infected ewes.
