Unlike foodborne pathogenic bacteria, little is published on food viruses and their research. This book is devoted to the study of molecular biology of foodborne viral pathogens and is divided into two sections. The first section outlines key molecular biological techniques that have been applied to foodborne viral pathogens research. The second section covers individual foodborne viral pathogens in relation to their classification, morphology, genome structures, biology, epidemiology, clinical features, pathogenesis, diagnosis, treatment, and prevention, among others.
