Antibodies to Leptospira serotypes were detected in sera from 15 (6.9 per cent) of 218 aborted fetuses, but were not detected in the sera from 196 non-aborted fetuses. Fourteen (6.4 per cent) sera from the aborted fetuses had antibodies to strains belonging to the Hebdomadis serogroup and 1 (0.5 per cent) had antibodies to a strain belonging to the Icterohaemorrhagiae serogroup. These antibodies were predominantly immunoglobulin M whereas in the dams, antibodies belonged to both immunoglobulin M and G classes.
