Effects of the composition of peritoneal dialysis fluid on chemiluminescence, phagocytosis, and bactericidal activity in vitro.

abstract：:Most Campylobacter jejuni strains are sensitive and most Campylobacter fetus strains are resistant to the bactericidal activity in normal human serum. We purified lipopolysaccharides from Campylobacter strains to determine whether their composition and structure relate to serum susceptibility. The lipopolysaccharide o...
