Abstract
There is disclosed an immunizing composition comprising a non-toxic polysaccharide isolated from gram-negative bacteria, especially from Pseudomonas aeruginosa, covalently coupled to a non-toxic protein from the gram-positive bacterium Micrococcus luteus by means of a 4-12 carbon moiety. To prepare the above immunizing agent, the lipid A portion of lipopolysaccharide from a gram-negative bacterium is separated to give a non-toxic polysaccharide. Reactive aldehyde groups are generated on the non-toxic polysaccharide by selective oxidation. The non-toxic polysaccharide is then covalently coupled to a non-toxic protein isolated from said gram-positive bacterium, Micrococcus luteus, by means of a polyfunctional compound having 4-12 carbon atoms and having at least two functional groups which are reactive to the aldehyde groups on the non-toxic polysaccharide and to the carboxylic groups on the non-toxic protein.
