We believe the result is a well-balanced exposition of immunologic diseases. This theme is constant throughout the basic immunology for the clinician. chapters on the allergic and immunologic diseases, and because The initial two sections on basic principles of immunology of the importance the editors attach to clinical immunology are followed by two sections that focus in detail on the role of as a therapeutic discipline, an extensive section is also devoted the immune system in defenses against infectious organisms.
