Clinical Microbiology for Diagnostic Laboratory Scientists

A modern, evaluative, and integrative approach to diagnostic microbiology encouraging problem-solving in the clinical laboratory context through the use of examples to illustrate clinical and diagnostic issues

Clinical Microbiology for Diagnostic Laboratory Scientists is designed to encourage readers to develop a way of thinking that can be applied to any diagnostic scenario in microbiology. Through consideration of a selected range of infections caused by pathogenic bacteria, viruses, fungi, protozoa, and helminths, the book encourages readers to explore connections between the available information about clinical symptoms, pathogenesis of infections, and the approaches used in laboratory diagnosis, in order to develop new insights.

The book begins with an introductory chapter that outlines the scope of clinical diagnostic microbiology and the key areas for the laboratory scientist to be aware of. The subsequent six chapters review a type of infection in depth, using particular pathogenic microorganisms to illustrate salient points. At the end of each chapter there are three exercises related to management of a diagnostic service and assessing the suitability of test methods to specific contexts. There are no right or wrong answers to these, but the reader can discuss them with their laboratory colleagues or university tutor.

• Makes extensive use of published research in the form of journal articles, publically available epidemiological data, professional guidelines, and specialist websites

• Stimulates the reader in critical appraisal of published evidence and encourages problem-solving in the laboratory

• Outlines the scope of clinical diagnostic microbiology and the key areas for the laboratory scientist to be aware of

• Considers topics relevant to professional scientists working in the area of diagnostic microbiology

Clinical Microbiology for Diagnostic Laboratory Scientists is ideal for post graduate scientists intending to pursue careers in diagnostic clinical microbiology and for biomedical scientists, clinical scientists, and full time students studying for upper level qualifications in biomedical science, microbiology, or virology.
