Influence of polyclonal immunoglobulins on the polymorphonuclear leukocyte response to lipopolysaccharide of Salmonella enteritidis as measured with luminol-enhanced chemiluminescence.

abstract：:Legionella pneumophila has been shown to possess multiple genetic loci that play roles in its ability to survive within host cells. The mil (macrophage-specific infectivity loci) mutants of L. pneumophila exhibit a spectrum of defects in intracellular survival in and cytopathogenicity to macrophages and alveolar epith...
