This new edition explores and provides an update on the biology and pathogenesis of human cytomegalovirus infection.  Modern techniques that are currently being utilized to investigate the molecular aspects of viral infection, as well as how these new research studies are leading to new approaches to mitigate disease, are also provided. Given the key role the virus plays in significant acute and chronic human disease in all stages of life, from newborns to seniors, the need for clear methodologies to further explore the biology of HCMV infection and mitigation strategies is readily apparent. Written in the highly successful Methods in Molecular Biology format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
