Medical Immunology and Microbiology Essentials is designed with the medical student in mind and emphasizes the critical concepts that must be understood to excel on the allopathic and osteopathic licensing boards. This book reflects 30 years of experience teaching in the field, converting the molecular complexities of the immune system into a memorable, logical engineering design. It then emphasizes how the anatomy and physiology of bacteria, viruses, fungi, and parasites predict the pathogenesis in the patient. While most review texts emphasize the management of a subject through rote memorization, this book encourages the integration of biochemistry, physiology, immunology, pathology, and pharmacology to help students think like a doctor and provide the basis for a lifetime of learning in the rapidly evolving discipline.
