Immunology: A Short Course, ?Seventh Edition introduces all the critical topics of modern immunology in clear and succinct yet comprehensive fashion. The authors offer a uniquely-balanced coverage of classical and contemporary approaches and basic and clinical aspects. As with the previous editions, the strength of the text is in complete review of modern immunology without burdening the reader with excessive data or theoretical discussions. Each chapter is divided into short, self-contained units that address key topics illustrated by uniformly drawn, full-color illustrations and photographs.This new edition of?Immunology: A Short Course Provides? a fully-revised and updated edition of the best-selling short course and review book for undergraduate and medical studentsContains a brand new art program to reinforce learningProvides shortened introductory chapters to ensure a thorough understanding of the basics of immunologyIncludes a plethora of student support including end of chapter summaries and review questions.Provides flexible, portable content: available in several e-formatsThis new edition provides students and instructors with one of the most comprehensive teaching and learning packages available for the teaching and learning of immunology.
