Abstract excerpt
We isolated lipopolysaccharide and capsular polysaccharide (K antigen)-defective mutants from two Klebsiella pneumoniae parental strains, and compared their ability to colonize in vivo the germfree chicken gut. The high-molecular weight lipopolysaccharide (LPS) (O antigen) was found necessary for the colonization while the capsular polysaccharide (K2 or K29) was not of importance.
