This lab manual teaches how microbiological principles should be applied in practice. The labs are specifically designed for allied health and nursing microbiology courses, offering students a foundation in the practical lab skills and knowledge they need to be successful in this profession. Coverage of disease-causing microorganisms is organized by organism first and then subsequently by the body system affected. Critical-thinking questions challenge students to apply chapter material. Case studies are presented at the end of each disease chapter. These questions and case studies help students develop critical thinking skills and also serve to generate class discussions.
