The book is divided into six sections:
Microbial biology
Infection and immunity
Bacterial pathogens and associated diseases
Viral pathogens and associated diseases
Fungal pathogens and parasitic infections
Diagnosis, treatment and control of infection
The major portion gives a organism-based systematic coverage of microbiology. Each organism is considered under a standard set of headings:
Description
Pathogenesis
Clinical features
Laboratory diagnosis
Treatment
Epidemiology
The section on immunology covers that part of the subject that is of direct relevance to the understanding of microbial infection.
