Antibodies to Leptospires in Sows Involved in Premature Birth and Still birth

Abstract

In 1978, of 279 parturient sows 43 were involved in premature bitrh and stillbitrh. They had no clinical signs until parturition. Autopsy revealed scattered small gray foci in the kidney of 2 sow. Serum antibody titers to serovarcanicolawere higher than 1: 1000 in most of the 43 sows.
In 1982, of 49 parturient sows, 7 were involved in. They had no clinical signs until stillbirth, presenting scattered small gray foci primarily restricted to the kidney at autopsy. Their antibody titer was 1: 8192 to serovarhebdomadis.
