title: Distribution of porin and lipopolysaccharide antigens on a Pseudomonas aeruginosa permeability mutant.
abstract: Pseudomonas aeruginosa common surface antigens were compared in a permeability mutant (PCC118) and its parent (PAO503). The distribution of lipopolysaccharide and porin antigens in the mutant supports the conclusion that beta-lactam permeability was affected by lipopolysaccharide-side chain presentation rather than by a change in porin number.
