    Abstract

    A patient had complete deficiency of the second component of complement associated with chronic vasculitis and increased susceptibility to infection. We discuss here results of the complement profile, histocompatibility typing, and studies of the functional properties of patient plasma or serum in chemotaxis and opsonization in relation to the disease entity and host susceptibility to infection.
