Preface to Case Studies in Infectious Disease The idea for this book came from a successful course in a medical school setting. Each of the forty cases has been selected by the authors as being those that cause the most morbidity and mortality worldwide. The cases themselves follow the natural history of infection from point of entry of the pathogen through pathogenesis, clinical presentation, diagnosis, and treatment. We believe that this approach provides the reader with a logical basis for understanding these diverse medically-important organisms. Following the description of a case history, the same five sets of core questions are asked to encourage the student to think about infections in a common sequence. The initial set concerns the nature of the infectious agent, how it gains access to the body, what cells are infected, and how the organism spreads; the second set asks about host defense mechanisms against the agent and how disease is caused; the third set enquires about the clinical manifestations of the infection and the complications that can occur; the fourth set is related to how the infection is diagnosed, and what is the differential diagnosis, and the final set asks how the infection is managed, and what preventative measures can be taken to avoid the infection. In order to facilitate the learning process, each case includes summary bullet points, a reference list, a further reading list and some relevant reliable websites. Some of the websites contain images that are referred to in the text. Each chapter concludes with multiple-choice questions for self-testing with the answers given in the back of the book. In the contents section, diseases are listed alphabetically under the causative agent. A separate table categorizes the pathogens as bacterial, viral, protozoal/worm/fungal and acts as a guide to the relative involvement of each body system affected. Finally, there is a comprehensive glossary to allow rapid access to microbiology and medical terms highlighted in bold in the text. All figures are available in JPEG and PowerPoint® format at www.garlandscience.com/gs_textbooks.asp We believe that this book would be an excellent textbook for any course in microbiology and in particular for medical students who need instant access to key information about specific infections. Happy learning!!

Schistosoma spp.
A 25-year-old male was admitted to hospital vomiting blood. On examination of the abdomen both the liver and the spleen were enlarged. A full blood count revealed a reduced hemoglobin level of 9 g dl–1 and the white cell differential showed a raised eosinophil count of 1.1 ¥ 109 L–1 (normal range
