| Abstract: | The following cell surface physicochemical characteristics were investigated inKlebsiella pneumoniae: surface charge, surface hydrophobicity by different methods, and accessibility of the lipid fraction of the outer membrane. The capsular polysaccharide, as well as the O-antigen repeating units of the lipopolysaccharide (LPS), conferred a hydrophilic, negatively charged surface to the bacterium, and a barrier to the dye congo red, which binds sites within the lipid fraction of the outer membrane (OM). |
