Abstract
The present invention provides gram-negative bacterial strains that produce substantially pure non-pyrogenic lipopolysaccharide or lipid A. The present invention also relates to a use of said strains for the preparation of non-pyrogenic DNA and use of the same for introducing endogenous or foreign genes into animal cells or animal tissue. Further, the present invention relates to a use of said strains for the preparation of non-pyrogenic recombinant mammalian, protozoan and viral proteins. Furthermore, the present invention relates to a use of said strains for the preparation of non-pyrogenic bacterial vaccines and vaccine vectors. Yet a further use of the present invention relates to a use of said strains for the preparation of non-pyrogenic bacterial proteins and polysaccharides antigens for use as vaccines.
