Abstract
Shigellosis is a leading cause of diarrhea in many developing countries and although the disease can be controlled and managed with antibiotics, the constant emergence of resistant species requiring ever newer antibacterial drugs make development of an effective vaccine necessary. The bacteria are highly contagious and since immunity to Shigella is serotype-specific a multi-serotype vaccine is required for adequate protection. Proteins encoded by Shigella invasion plasmid, which are part of the Type Three Secretion System (TTSS) of this bacteria, are good candidate as vaccine targets since they are both immunogenic and conserved between different Shigella species. The advent of molecular farming, which is a low cost system, has opened up new venues for production of recombinant proteins. In view of the difficulties encountered in expressing IpaB in Escherichia coli (E. coli), the feasibility of the expression of this protein in tobacco has been investigated.
