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.
在218例流产胎儿的血清中，检测到15例（6.9%）存在钩端螺旋体血清型抗体，但在196例未流产胎儿的血清中未检测到。流产胎儿的14例（6.4%）血清中有针对七日热血清群菌株的抗体，1例（0.5%）有针对出血性黄疸型血清群菌株的抗体。这些抗体主要为免疫球蛋白M，而在母畜中，抗体同时属于免疫球蛋白M和G类。
