摘要

An inactive form of the Corynebacterium pseudotuberculosis phospholipase D (PLD) gene was constructed and expressed in a PLD-negative strain (designated Toxminus) of C. pseudotuberculosis. Antibody responses specific to Toxminus and both Toxminus and PLD proteins were detected in sheep following oral administration of Toxminus or Toxminus expressing the PLD toxoid, respectively. However, only those sheep vaccinated with Toxminus expressing PLD toxoid were protected against wild-type challenge. These results confirm the importance of PLD as a protective antigen and demonstrate both the potential for developing an oral caseous lymphadenitis vaccine and C. pseudotuberculosis Toxminus as a live vaccine vector.
