Cloning and Expression of B. mellitensis bp26 Gene in Lactococcus lactis as a Food Grade Vaccine

摘要

Background:Brucellosis is still an important health problem in under developing countries and researches for finding efficient vaccine are going on. Brucella melitensis (B. mellitensis) bp26 gene is a good candidate for brucellosis vaccine and investigations showed that Lactococcus lactis (L. lactis) with several positive characteristic are attractive for protein expression as a live delivery vectors. These fast growing bacteria need no aeration, are easy to handle, have no exotoxin, endotoxin and protease, so the cost of culturing is inexpensive.
