A vesicle Preparation produced by genetic engineering from a modified Strain of a Gram negative bacterium

摘要

? A Gall bladder Preparation obtained by genetic engineering from a modified Strain of a Gram negative bacterium which is characterized in that the preparation can be obtained using the following Process: (a) a process of bottom-up Regulation of the expression of Protective OMP antigens within the Gall bladder Preparation comprising the steps of identifying diCho antigen, a modified by Genetic Engineering bacterial Strain rnu00e1s looking to introduce a strong Promoter Sequence upstream of the gene encoding the Antigen so that the Gene is expressed at a higher level than in the gallbladder is not modified, and has CER vesicles From This strain.
