[Research on phagocytosis].

A problem of particular importance, but also particularly difficult, is the investigation of the phagocytic system, considering its implication in various aspects of pathology. This has determined the authors to present the major modalities for the investigation of phagocytosis. They recommend as a diagnostic method for garnulocytopathies (including a series of metabolic abnormalities. Of the leucocytes with implications for the bactericidal capacity), a testing of leucocyte bactericidal capacity. The test with nitroblue tetrazolium is also recommended, for the screening and differential diagnosis of fever conditions of infectious origin and other etiologies.
