Infection and Immunity, third edition, describes the main causes of infection that our bodies have to battle against - from bacteria to viruses, fungi to protozoa - and explains the intricate and fascinating ways that our bodies respond to infection - from detection of these potentially dangerous organisms, to their ultimate elimination. Presenting a fully-rounded, perfectly-balanced overview of the field, the book also explains how diseases spread, and what measures we can take to control this spread - from vaccination to increased awareness through public health initiatives. With examples of infectious diseases from across the world, Infection and Immunity is perfect for biomedical science, bioscience and microbiology students who need to understand what causes infection, and how our immune systems respond.
