B    58.   Disease characterized by severe recurrent and lingering bacterial
           infections beginning in infancy, or early childhood. Causative agents
           are most often members of the Enterobacteriaceae (e.g. Serratia,
          Escherichia, Klebsiella, etc or S. aureus. The patient's neutrophils are
          adequate for chemotaxis and pathogen ingestion.
C   59.   The patients frequently exhibit a state of neutropenia coupled with
          recurrent severe attacks of bacterial sinusitis and pneumonia and/or
          deep tissue abscesses accented by mild bleeding episodes. Presence of
          normal microbe ingestion, abnormally large lysosomes, deficient
          chemotaxis and diminished degranulation of the neutrophils
          characterize neutrophils after phagocytosis.
A   60.   Inherited condition most frequently recognized by patients increased
          susceptibility to Candida albicans infections. Neutrophil chemotaxis,
          phagocytosis and degranulation activity is normal. Microbe killing is
          defective. Diagnosis is made in part by testing levels of specific
          enzyme-associated activity in blood cells on the blood film.
