Fulminating Ulcerative Colitis

Significant differences in perinatal mortality among three areas of Lincolnshire over a three year period are shown to be due to variation in stillbirth rate. Investi- gation of possible causes of this showed that there was a significantly higher incidence of cytoplasm-modifying antibody to T. gondii in the women whose babies had been stillborn, when compared with a group of mothers who had been delivered of live babies in the same month and in the same place. The two groups did not differ greatly in age, parity, or in any other respect. The hypothesis that toxoplasmosis may have been the cause of these stillbirths is discussed.
