title: [Direct IgG-mediated reactivity of human neutrophils to Corynebacterium diphtheriae peptidoglycan].
abstract: The direct and IgG-mediated reactivity to C. diphtheriae peptidoglycan in the system of neutrophilic phagocytosis was studied. Peptidoglycan treated with IgG (2-20 mg/ml) isolated from commercial immunoglobulin stimulated the reduction of nitro blue tetrazolium by human neutrophils. Direct (IgG-independent) reactions were much less intensive. The problem of normal IgG opsonizing C. diphtheriae peptidoglycan is discussed.
