Prepartum changes of plasma concentrations of prostaglandin F and 13,14-dihydro-15-ketoprostaglandin metabolites in pregnant animals exposed to Sarcocystis cruzi or Campylobacter fetus.

Pregnant cows at 4- to 5-months' of gestation were exposed to Sarcocystis cruzi or Campylobacter fetus. Plasma prostaglandin F (PGF) and 13,14-dihydro-15-ketoprostaglandin metabolite (PGM) concentrations were determined at intervals from before exposure until abortion or parturition. The plasma PGF concentration of pregnant infected cattle remained at 0.02 +/- 0.04 ng/ml until 24 to 48 hours before abortion or parturition when it increased 5-fold to 0.11 +/- 0.12 ng/ml. The plasma PGM concentration of these cattle remained at 0.10 +/- 0.07 ng/ml until 24 to 48 hours before abortion or parturition when it increased over 10-fold to 1.36 +/- 0.60 ng/ml. This change in PGF and PGM was similar to that of cattle exposed to each of the infective agents and to that of normal cows at parturition. Thus, changes in PGF and PGM concentrations in bovine plasma cannot be used as a diagnostic tool to determine fetal distress or fetal death for these infections.

Intrauterine infection with mumps virus.

The histopathologic study of 3 cases of gestational mumps is presented. The tissue studies was obtained from a spontaneous abortion (case 1) and from 2 therapeutic abortions (cases 2 and 3). Severe placental and fetal lesions were observed, indicating a probable association with maternal mumps. The main placental lesion was a diffuse proliferative necrotic villitis with severe lesions in the fetal vascular circuit, probably the cause of death. In the fetal viscera, areas of necrosis and mineralization were observed. Viral inclusions identical to those described in mumps infection were observed in the chorionic and fetal tissues.
