Abstract
Boophilus Yolk pro-Cathepsin (BYC) is an aspartic proteinase found in Boophilus microplus eggs that is involved in the embryogenesis and has been tested as antigen to compose an anti-tick vaccine. The vaccine potential of a recombinant BYC expressed in Escherichia coli (rBYC) was investigated. rBYC was purified and used to immunize Hereford cattle. The sera of bovines immunized with rBYC recognized the native BYC with a titer ranging from 125 to 4000. Furthermore, immunized bovines challenged with 20,000 larvae presented an overall protection of 25.24%. The partial protection obtained against B. microplus infestation with the recombinant protein immunization was similar to the already described for native BYC immunization.
