This book provides background information about the various types of microbes, how they affect people, and how to prevent the spread of the infections they cause. Microbiology is defined broadly to include parasitology with descriptions of the principal diseases caused by protozoa, worms and insects. Both clinical and community aspects of infection management are considered in this practical book. This book should be of interest to students in nursing and other health sciences, especially dieticians, nutritionists and hygienists.
